Abstract: DSMC method'is a physically based probabilistic simulation method. Among the numerous analytical, numerical and simulative methods, DSMC method is the only Procedure capable of simulating the flow of real gas with complex three-dimensional configurations. The method is supported by experiments both on the level of global macroscopic characteristics and the level of microscopic characteristics such as the velocity distribution functions. The present paper reviews the recent development'of the DSMC method, in...
