| Abstract: | In this paper, the axial symmetrical NS equations have been numerically solved using the finite difference method,an energy source term and eleven species chemical dynamic model are consi dered. The absorption coefficient of air to laser energy is calculated by the Hydrogen like theory. The computational program has been accomplished for simulation to the interaction between a powered focused Laser and the supersonic/hypersonic flow past a blunt body. The results of the interaction between a high powered focused laser and the hypersonic flow past a sphere head are presented in this paper. |
