| Abstract: | The symmetric thermochemical nonequilibrium radiation flow is simulated numerically. The full Navier Stokes equations are taken as the governing equations. The two temperature and eleven species gas model is considered. The improved Nicolet "one temperature" radiation model is used. NND scheme for shock capture and time preconditional matrix technique are used for numerical solution. The result of radiation heat is got for contrasting with experiment result. |
