Recent Developments in Aerodynamics

Aerodynamics is a branch of fluid mechanics that deals with the motion of air and other gaseous fluids and the forces acting on bodies in motion relative to such fluids. Aerodynamics are classified according to Mach number into incompressible subsonic, compressible subsonic, transonic, supersonic and hypersonic aerodynamics. Aerodynamics can be divided into different forms of internal or external aerodynamics. For example, the study of flow properties inside a gas turbine or rocket engine is an example of internal aerodynamics that is important in accurately estimating thrust force. Examples of external aerodynamics include the flow around the body of airplanes, helicopters, space capsules, cars, rockets and missiles, trains, ships, wind turbines, and even such structures as bridges and tall buildings, which often have to withstand strong winds. Since the first human flights until today, aerodynamics has been growing and developing rapidly.

Aerodynamics is one of the applied sciences in engineering that pursues several goals such as estimating forces, moments on objects moving in the air, or estimating heat transfer from these objects. Aerodynamics investigates how gases interact with moving bodies. The main purpose of aerodynamics in most cases is to reduce drag forces and increase lift force, which can lead to less fuel consumption in vehicles and achieving the greatest speed. Of course, in some special cases, such as hypersonic aerodynamics, there is a greater interest in increasing drag to reduce the adverse effects of aerodynamic heating. Another goal of studying aerodynamics is to obtain the details of the flow around flying objects. For example, the correct operation of a control rudder or flap in a supersonic aircraft, or the recognition of the phenomenon of blackout during spacecraft reentry, which occurs under the influence of aerothermodynamic heating and plasma formed around the antenna, is of great importance.
