Numerical Investigation on Chemical Equilibrium Slip Flow of High Altitude and Large Mach Number

摘要

In the flight of hypersonic near space vehicle from 60km up to 100km high, the influence of real gas effect, rarefied gas effect, and Mach number effect cannot be simulated completely by the ground test. In this paper, the selection of computational model is introduced, and then carried out the numerical research on slip flow field characteristics coupling with chemical-equilibrium effect under large Mach number of high altitude.
