introduction：aerodynamics： The study of the motion of gaseous media with thermal effects under the assumption of continuum。It is based on classical fluid mechanics﹐Developed by combining thermodynamics and chemistry。What is commonly referred to as aerodynamics assumes that gases are non-viscous﹑Nonheat transfer。In aerodynamics﹐The flow is divided into subsonic flow according to the velocity of motion﹑Transonic flow﹑Supersonic flow and hypersonic flow﹔According to the changing characteristics of flow in space, it can be divided into one-dimensional flow﹑Two dimensional flow and three dimensional flow﹔According to whether the flow at each point in space changes with time, it is divided into steady flow and unsteady flow。In accordance with
