Abstract

In this paper, the dynamic process driven by one-dimensional piston in stroag gravitational field was studied on the Cartesian, cylinderical and spherical coordinates. The gasdynamic equations were numerically solved by the characteristic method. The solution which satisfies the velocity condition at piston aad the boundary conditions nect the flow region and,the quiet region is btained. The present paper analyses especially the influence of coordinate systems on the field of compressible flow, uniform flow ana raretacuon mow region, the shock velocity and the temperature distnuution at the piston.
