Hypersonic Heat Transfer
At very large flight speeds, i.e. hypersonic speeds, which describe rocket motion, as well as space vehicle entry into dense atmospheric layers, the ambient gas undergoes not only density change, but also a significant temperature increase. The latter causes different physical-chemical reactions. Substantial part of kinetic energy associated with the flight speed is converted into heat and chemical energy. Hypersonic Heat Transfer is a special subdivision of aerodynamics that studies gas motion laws, as well as interaction between gas and a body moving in it at a hypersonic speed.
