Abstract

Abstract

A general Godunov finite difference schemes-WENO schemes which had fifth-order accuracy was used to make a numerical calculation for 2-dimensional axis symmetrical laser-supported plasma flow field under laser ablated solid target and laser ablated propulsion efficiency parameters(mechanical coupling coefficient etc.) was obtained by the simulation. The models of the calculation of ionization degree of plasma and the interaction between laser beam and plasma and the simplified eos(equation of state) of plasma were considered in the simulation. Comparision of simulation and calculation results shows that the different materials of target and the laser parameters (intensity, wave length etc.) and the geometry of target are the main factors which influence the laser propulsion efficiency.
