Abstract

In article it is stated statements of problems and results of numerical modeling of processes in Piston Gasdynamic Unit intended for reception of a supersonic stream of gas for development of products of the space-rocket mechanics. The technique of the decision of three interconnected physical problems of calculation of dynamics of movement of the piston has been developed. The algorithm of parallel calculations with use of Message Passing Interface (MPI) technology MPI for problem calculation on multiprocessing computing systems is realized. The received results of computational fluid dynamics have been comparison with results of experiment.
