The present communication is designed to elucidate the flow attributes of micro-polar non-Newtonian liquid over stretching/shrinking surfaces. In addition, we have observed the stagnation aspect along with the velocity slip condition on the momentum field. The Fourier law of heat conduct, along with a physical aspect of stratified and heat generation absorption, are then used to model the temperature equation. The Buongiorno nanofluid model is used to study additional transport features. After a discussion of PDEs using similarity transformation, mathematical formulations of the given problem are supported in the form of an ordinary differential system. The solution of modeled governing equations containing physical effects is simulated by using the shooting method in conjunction with RK- Method. The significant effects of flow parameters that are associated with velocity, temperature, and concentration distribution for low and upper branch solutions are revealed through graphs and tables. Quantities of engineering concerns like skin friction coefficient and Nusselt number are also compared with previous results of critical values. Furthermore, it should be considered that as the micro-pole parameters are increased, the local skin friction coefficient and the local Nusselt number amplitude also rise.

1 Introduction

Magnetic fluid dynamics is the foundation for improving the progression of high conductivity fluids in the direction of the magnetic field. The study of magnetic field flows, both Newtonian and non-Newtonian, has an extensive variety of applications in industry and engineering. The cooling system fluid metal, MHD generators, liquid beads and sprays, accelerators, atomic reactors, nutrient preparation, the oil industry, microelectronics equipment, geothermal energy extraction equipment, and so on are all examples of MHD applications. Many scientists believe that it has great uses in micro-skipping and slip velocities explored the fluid analysis of small horizontal heat shifts. Sliding flow plays a key role in small-scale instruments, hard disk scale valves, and micro-scale wells. [1] explain the two parallel bands between the secondary fluid magnetic flow force serialized stream. [2] the semi-inverse solution of nanometer uniform magnetic flow on the stretched surface of the secondary fluid was studied. [3] observed an irregular magnetic-fluid-dynamic hybrid convector of a secondary nanofluid caused by thermal radiation in a stretched plane. Recently, [4] analysis of the magnetic flow of the two nanofluids due to non-linear stretching of the surface. [5] examines the magnetic flow of nanofluids in tubes. [6] considered the entropy generation of nanofluids and MHD streams on non-linear stretched surfaces was studied. [7] discuss the rotational flow of water-based nanofluids in parallel plates. [8] analyzed the influence of pseudoplastic fluids loaded with antiparticles on the heat transfer of MHD flow. [9] a three-dimensional MHD stream of Maxwell nanoflow was analyzed by convection boundary. [10] speculate on the magnetic flow of the secondary fluid above the stretching plane. [4] the magnetic fluid dynamics of the secondary nanofluid were analyzed due to the non-linear stretching of the surface. [11] also studied the computational aspects of MHD streams near rotating disks. Many comparative investigations are considering the significance of fluid motion through various physical phenomena that can be found in [1214].

Thermal rays play an important role in space technology and high-temperature operations. When the temperature changes greatly, the linear thermal radiation can cause significant errors. To overcome this inaccuracy, non-linear thermal radiation was taken into account. The chattels of chemical processes and the flow of thermal radiation to the externally stretched surface were explored by [15]. Many scientists have conducted several studies to emphasize the significance of thermal radiation [1618].

Natural convection and forced convection combine to form mixed convection, which is among the transmitting phenomena. Mixed convection occurs in many natural and engineering applications during transport. Industrial and technological processes, including exposure to the wind in the solar central receiver, fan-cooled electronics, and cooling of nuclear reactors in the event of downtime. [19] check past mass exchange and Hall effects semi-infinite vertical band magnetic fluid free heat transfer flow. [20] studied the influence of conical micro-polar fluid flow on the stretched surface. Micro-polar fluids are those that contain micro-components that can be rotated, and whose appearance can affect the flow of fluid power so that it can be non-Newtonian. Different types of non-ideal fluids can be seen in regular life, such as macromolecules, animal blood, and shampoos.

Analysis of Dual Solutions in MHD Fluid Flow with Heat and Mass Transfer Past an Exponentially Shrinking/Stretching Surface in a Porous Medium was studied by [21]. Using a conducting fluid to pass through a sheet that was simultaneously stretching and contracting exponentially, researchers examined the nature of dual solutions in the hydromagnetic boundary layer. Investigation of the combined effects of the electrically conducting water-based nanofluid parameters, thermal radiation, the porous medium, convective heating, viscous dissipation, magnetic field, and the nanofluid on the dimensionless velocity, temperature, and rescaled nanoparticle volume frame is the aim of the current work. Readers are directed to [2234] and any cited references therein for more information.

This study’s objective is to numerically investigate micropolar nanofluid flow with slip boundary conditions. The first step in this is mathematical modeling for the MHD nanofluid flow with a nonlinear condition. Finally, use a shooting scheme to solve numerical results. The remaining sections of the document are arranged as follows; in Section 2, flow configuration and governing equations are described. The numerical scheme is carried out in Section 3. Section 4 conducts a thorough analysis of the findings. Section 5 also discusses the conclusion.

2 Flow analysis and development

This study investigates the steady, 2D, and double stratified flow of an electrically conductive micropolar nanoparticle on a stretching/shrinking surface. It is worth noting that the heat and mass transport phenomena are investigated when velocity slip and thermal generation/absorption are considered (see Figure 1).

FIGURE 1. An illustration of flow analysis.

The following are the governing equations for heat and mass transfer:

ux+uy=0,(1)
uux+vuy=(νf+kfρf)²uy2+kfρfNyσB02ρf(uu)+ududu,(2)
uNx+vNy=γf(jρ)f2Ny2²+kf(jρ)f{2N+uy},(3)
uTx+vTy=kf(ρcp)f2²Ty2²+(ρcp)p(ρcp)f{DBCyTx+DTT(Ty)2}+Q*(ρcp)f(TT),(4)
uCx+vCy=DB²Cy2+DTT2²Ty2².(5)

The associated practical boundary condition is given as

Aty=0,u=uw(x)+uslip,v=0,N=nuy,T=Tw(x)=T0+m1x,C=Cw(x)=C0+n1xAsy,uu=bx,N=nuy,T=T=T0+m2x,C=C=C0+n2x(6)

where

uw(x)=bx,uslip=L*[(μ+k)uy+kN].(7)

While using the similarity transformation

η=(bνf)12y,u=axf(η),v=(bνf)12f(η),N=(b3³νf)12xg(η),θ(η)(TwT)=(TT),φ(η)(CwC)=(CC).(8)

Using Eq. into Eqs 25 we have

(1+K)f+fff2+M(1f)+Kg+1=0,(9)
(1+K2)g+fgfgK(2g+f)=0,(10)
θPr(fθθf+1f)+PrNbθφ+PrNtθ2+PrQθ=0,(11)
φ+Sc(fφfφ+2f)+NtNbθ=0.(12)

The corresponding non-dimensional boundary conditions are expressed as follows:

f(0)=0,f(0)=λ+α[1+K(1n)]f(0),g(0)=nf(0),θ(0)=11φ(0)=12,f()=1,g()=0,θ()=0,φ()=0.(13)

The material parameter, magnetic parameter, Eckert number, Schmidt number, Brownian motion number, Prandtl number, thermophoresis number, thermal stratification, and solutal stratification are among the non-dimensional parameters used in our analysis. The mathematically defined as:

K=kfμf,M=σB02ρb,Pr=Cpμk,Sc=νD,Ec=uw2Cp(TwT),1=m2m1,Nb=(ρcp)pDB(CwC)(ρcp)fνf,Nt=(ρcp)pDT(TwT)(ρcp)fνfT,2=n2n1.(14)

3 Physical quantities

The surface shear stress is determined by

τw=((μ+k)uy+KN)y=0.(15)

Skin friction is defined as

Cf=τwρfuw2.(16)

Using eqs. (8)-(10) into eqs. (15)-(16), we have

ReCf=[1+K(1n)]f(0).(17)

and the heat transfer rate is given by

qw(x)=kf(Ty)y=0.(18)

after using similarity transformation we have

qw(x)=kfm1bvfxθ(η).(19)

and local Nusselt number written as

Nux=xqwkf(TwT).(20)

by using similarity transformation, we have

Nux=111θ(0).(21)

where 1=m2m1

4 Numerical scheme

Finding a precise solution to the current governance model equations’ problems is challenging due to their complexity and high nonlinearity. Therefore, the bvp4c method is used to calculate a numerical solution for the ode under boundary conditions. In this case, we first defined the new variables in accordance with the control equations’ order and changed the PDE system into a first-order ode. To adapt to the First-Order system, we use the following variables.

f=y1,f=y2,f=y3,g=y4,g=y5,θ=y6,θ=y7,φ=y8,φ=y9.(22)

Thus, the reduced system of First-Order differential equations becomes:

y1=y2,y2=y3,(23)
(1+K)y3+y1y3y22+Ky5+M(1y2)+1=0,(24)
y3=11+K[y1y3+y22Ky5M(1y2)1],(25)
y4=y5,
(1+K2)y5+y1y5y2y4K(2y4+y3)=0,(26)
y5=11+K2[y1y5+y2y4+K(2y4+y3)],(27)
y6=y7,(28)
y7+Pry1y7Pry2y6Pr1y2+PrNby7y9+PrNty72+PrQy6=0,(29)
y7=Pry1y7+Pry2y6+Pr1y2PrNby7y9PrNty72PrQy6,(30)
y8=y9,(31)
y9=Scy2y6Scy1y9+Sc2y2NtNby7,(32)

And the boundary conditions are

y0(0)=0,y0(2)=λ+α[1+K(1n)]y0(3),y0(4)=ny0(3),y0(6)=11,y0(8)=12,y(2)=1,y(4)=0,y(6)=0,y(8)=0.(33)

This is a very effective numerical procedure for handling BVP problems. This scheme uses a finite difference code to perform a Level 3 Lobatto IIIa formula. In this approach, we have to select an appropriate finite value of, say between 10 and 35. On the other hand, the grid is chosen and error control depends on the residue of the continuous solution. The current findings are compared to those found in the literature [21] for validation, as shown in Table 1.

5 Result and discussion

This section analyzes the computational findings in terms of nondimensional velocities, f(η), g(η), concentration ϕ(η), temperature θ(η), skin friction coefficient, and rate of heat transfer with distinct values Prandtl numberPr, the material parameter K, slip parameter α, stratification parameter λ, Eckert number Ec, magnetic number M, Brownian motion number Nb, thermophoresis numberNt, Schmidt number Sc, Temperature proportion ratio parameterQ.

Figures 26 show the relationship between boundary layer thickness and velocity f(η) against the M, K, and n, while the other parameter remains constant. Figure 2 is drawn to witness the impact of magnetic parameters on the dimensionless velocity distribution f(η). Curves show that when the magnetic parameter is increasing, the profiles of velocity distributions in the first solution are increasing but they have opposite behavior in the second solution. The significant effect of material parameters on dimensionless velocity is shown in Figure 3. A significant decline in the profiles of the first solution as well as in the second solution when a suitable enhancement happens in the values of a material parameter. The velocity distribution for various values of slip constraint is shown in Figure 4. The graphs show that a dual solution for shrinking flow inside the boundary layer region exists. In the first solution, growing the value of the slip parameter improves velocity profiles, whereas the second solution has the opposite effect. Figure 5 describes the disparity of velocity distribution with changing values of stratification parameters. We note that as the stratification parameter rises, there a decline happens in the upper branch solutions but the outcomes are fairly reversed for the second solution. Figure 6 shows the comparison of both solutions for different values of n. It is clear that for the upper branch solution, with the growth in f(η), dimensionless velocity profile upsurges, while the effect is different for the second solution.

The characteristics of angular velocity distribution g(η) are illustrated graphically through Figures 711 for numerous quantities of physical parameters M,K,α,λ and n. In each Fig, we observe the dual nature of angular velocity distribution for shrinking flow. The influence of magnetic parameters on dimensionless angular velocity inside the boundary layer is displayed in Figure 7. As expected, the angular velocity curves show an increasing behavior with an uplifting value of the magnetic parameter in the first solution, while in the second solution, the profiles show a decreasing behavior when we grow the value of the M. The computed result of g(η) for numerous values of the K is illustrated in Figure 8. According to this figure, a straight line is displayed on a graph when K = 0, for both the solution, but when K = 1, 3 there is a comparison made for dimensionless angular velocity distributions. It is seen that dimensionless angular velocity profiles decrease in the case of the first solution due to the magnetic effect and the results are the same for the second solution. Figure 9 reveals the outcomes of the slip parameter on angular velocity distribution. As you have seen, the αsignificantly affects the angular velocity curves and shows an increasing trend for an upper solution but the results are different in the lower solution. Figure 10 display the variation of dimensionless angular velocity profiles within the boundary layer for numerous values of stratification parameters. It is seen from this figure that all curves approach the far-field boundary conditions asymptotically. From the curves, a comparison is made for dimensionless angular velocity profiles with different values of stratification parameters. In the case of the first solution with a magnetic effect, the angular velocity profile increases but the results are quite opposite in the case of the second solution. Figure 11 illustrates the dual g(η)for different α. Again, we notice a similar behavior in both solutions with uplifting values of g(η).

Figures 1216 portray the characteristics of θ(η) are illustrated graphically for several values of physical parameters M,K,n,Pr and Q Figure 12 reveals the dual θ(η) for different M. As expected, a decline in temperature profile is seen for growing values of θ(η) in the first solution, while an inverse is noted in the second solution. The temperature distribution θ(η) with different Kare is demonstrated in Figure 13, which displays that as the material parameter boosts the θ(η)show an increasing trend in both solutions. The effects of various n values on temperature profiles, for shrinking cases, are shown in Figure 14. Furthermore, the first solution’s curves demonstrate a decline in energy distribution as n increases, but the results for the second solution, which promotes a higher thermal flow rate between the surface and fluid, are noticeably different. The dual θ(η)for specific entries of the Prandtl number Prare shown in Figure 15. With the rise of θ(η), a decline is seen in the upper branch solution, while the inverse behavior happens in the case of the lower branch solution. The variation of dual θ(η) for changing values temperature proportion Q is plotted in Figure 16. We analyzed that, as the Q is upsurges the temperature distribution increases in both solutions.

The dual concentration distributions are displayed in Figures 1720 for different values of parameters Q and Sc. The impact of M and K on concentration profiles is demonstrated in Figures 17, 18 by other parameters keeping fixed. We observed that the larger M gives the decline of Q in the case of the first solution. Furthermore, we see a growing trend in concentration distribution ϕ(η) or larger M. In addition, it is extracted from Figure 18 that the concentration profiles increase by uplifting values of material parameter K in both solutions. The variation of nondimensional concentration distributions ϕ(η) along with numerous values of n and Sc are illustrated in Figures 19, 20 respectively. It is found in Figure 19 that the ϕ(η)decline with the growing values of n for the first solution. However, an inverse behavior is noted for the second solution. Similarly, the same behavior is noticed in concentration distributions for various values of Schmidt number Sc, as shown in Figure 20. Moreover, Figures 21, 22 are drawn with different values of M and K. Figure 21 draws to witness the effect of M on wall shear stress. A massive enhancement in critical values is noted with larger values of M which enhances the existence domain of dual solution. The impact of K on skin friction ϕ(η)against the stratification parameter is exhibited in Figure 22. Moreover, we described the existence of a dual solution in the case of shrinking flow. As the K is increased, the magnitude of critical values grows. Furthermore, a substantial enhancement in skin-friction coefficient is examined for growing values of K, as depicted in Figure 23. The variation in heat transfer rate at the surface ϕ(η)against shrinking parameters for numerous values of K and M are demonstrated through Figures 23, 24.

6 Conclusion

In this research work, we erect a dual solution close to the stagnation point of the micro-polar fluid under the action of nonlinear tensile/shrinkage sheet magnetics. Graphical results and discussion for fluid particles micro-floating, tensile/contraction parameters, and magnetic parameters invoke the thermal flow rate. For computational purposes, using MATLAB bvp4c scheme. As can be seen, MATLAB bvp4c is time-saving, efficient, durable, and fast convergence, and has good consistency with earlier studies. It should also be esteemed that the local skin friction coefficient and the local Nusselt number amplitude increase with increasing micro-pole parameters. The range of skin friction and solution is expanded by the application of magnetic force. The fluid moves more quickly when nonlinear stretching and contracting parameters are used. As the material parameter K rises, resistance close to the surface increases.
