ABSTRACT=<p>Heat transport over an upper paraboloid horizontal surface of revolution (UPHSR) has attracted much interest of the researchers and aero dynamists. The flow of fluid around the pointed surface of rocket, bullets, bonnet, and fighting aircrafts exhibits flows in which engineering parameters like shear stresses and Nusselt number significantly contributed. Therefore, the study of fluid comprising heat generation/absorption, Lorentz forces, and chemical reaction over a radiative UPHSR is conducted. The basic constitutive relations are transformed into dimensionless version via similarity variables and tackled numerically.

Furthermore, Prandtl, Biot, and thermal radiations effects are observed to be of huge significance in the analysis of heat transfer.
