Numerical Simulation Research On The Interaction Between Jet Induced By Laser And Supersonic Flow Feild

The purpose of this thesis is to investigate the interaction between material vapor jet and supersonic flow when intense laser incident the missile. The 2D and 3D N-S equations included real gas model and B-L turbulence model are numerical solved used finite volume method (FVM).NND scheme is used for the spatial discretization of the equations.The LU-SGS scheme is employed for the time discretization when the equations are steady and two-order Runge-Kutta scheme when unsteady. Based on Knusen's theory,a model including laser reflection has been proposed to calculate the jet's properities induced by intense laser. In the last chapter,some cases are numerical simulated and compared on different conditions ,such as incidence position, laser intensity, mach number and angle.
