Practical use of parallel computing for numerical simulation of interaction between air laser plasma and a surface

A two-dimensional axisymmetric computational model is developed to describe propagation of laser induced plasma and its interaction with a surface. The model is intended for calculation of momentum coupling coefficient. Parallel computing was carried out on cluster created in Radiative Gas Dynamics Laboratory of IPMech RAS.
The results of the numerical calculations for different initial conditions and forms of the surface are presented. The calculated values of momentum coupling coefficient are close to experimentally measured ones in Japan and the USSR.
Essential features of the developed parallel algorithm are discussed. An investigation of the parallel speed-up got on the cluster and efficiency of the used algorithm were performed.
