Abstract
Abstract
Numerical simulations were conducted for calorically perfect gas and high temperature thermochemical nonequilibrium gas by CFD methods. Hypersonic Flow with High Temperature Thermochemical Nonequilibrium Effect was studied. The results showed that high temperature effects change the flow field and reduce heat transfer observably. For high temperature flow the kinetic energy associated with hypervelocity flight is converted into increasing the temperature of the air and endothermic reactions including dissociation and ionization of the air past shock. Thus, temperature in the shock layer dramatically decreases. All these works build foundations for further hypersonic aerodynamical computations and engineering applications.
