Abstract

The direct simulation Monte Carlo method is used for numerical simulation at the molecular-kinetic level the development of the Kelvin-Helmholtz instability between two supersonic monatomic gas flows. To induce flow instability, no artificial disturbances are introduced and the waves of instability are developing from the statistical fluctuations inherent in the DSMC method. It is shown that modeling using the DSMC method makes it possible to fully reproduce the Kelvin-Helmholtz instability pattern observed in physical experiments and continuum simulations with the rapid growth of instability waves, the formation of vortex structures, vortex interaction and their sequential merging.
