| Abstract: | In this paper, the numerical method is studied to calculate the hypersonic nonequilibrium viscous flow over a slender body with blunt nose. The detail of solving continuity equation and normal momentum equation in coupled way is described, as well as the mathematical method of dealing with slip boundary conditions at high altitude. The results of numerical solution indicate that the method is successful for marching forward to afterbody region about 30 times of nose radius. |
| Keywords: | Hypersonic flow Viscous flow Non-equilibrium flow Finite difference theory. Blunt body. |
