Aerodynamics is the branch of dynamics that deals with the motion of air and other gaseous fluids and with the forces acting on bodies in motion relative to such fluids. The Latin word for aero means air, and the Latin word for dynamics means power. Steady aerodynamics this term is used to describe situations where there is no rapid change in properties over time. For example, an aircraft cruising straight and level in the upper …showed first 75 words of 837 total…

A quasi 1D Nozzle simulation with finite-rate chemistry and ionization has been developed. (ENO-van Leer's schemes). The extension regarding two-dimensional flows is implemented and is in the process of validation. (L. Walpot) In conclusion aerodynamics is a very interesting subject. Aerodynamics has to deal with lots of thing like cars, aircrafts, spacecrafts and lots of other things.
