Abstract

The article presents the direct simulation results of two-phase mixtures with phase transition shock tube in dodecane, two-phase expansion tube in water and 2D heat and mass transfer in a vertical channel with sodium. For two versions of the code for CPU and GPU calculations possess efficient scaling in the wide range of grid sizes. Scaling for CPU version of the code is close to ideal and does not depend from the grid size and the number of nodes. Efficiency of scaling for GPU version of the code is limited by the size of calculation region per 1 node and could be varied for different models of processor. The value of scaling factor was demonstrated.
