Description
A general Godunov finite difference schemes-WENO (weighted essentially non-oscillatory) Schemes which have fifth-order accuracy is used to make a numerical calculation of 2-dimensional axis symmetrical laser-supported plasma flow field under laser ablated solid target. 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 are considered in the simulation. Variation of plasma field parameters during and after laser interaction is also obtained. the comparison of simulation results and theoretical model shows that the results of theoretical model which has no consideration of 2-D expansion effect greater than the results of 2-D simulation, and there is no order difference in magnitude. The results of simulation are creditable. (authors)
