| Abstract: | During the design of complex reentry vehicles,it is important to predict the aerodynamic force and heating.But different results may be obtained while using different thermal and chemical gas models in the numerical simulation.So the effect of gas models on the aerodynamic force and heating must be taken into account.This paper focuses on the aerodynamic force and heating of complex reentry vehicles varying with the thermo-chemical equilibrium gas model and the two-temperature thermo-chemical non-equilibriu... |
