【 摘 要 】
The simplest shear flow - a two-dimensional (plane) nonstationary mixing layer - is considered. Results obtained from the direct numerical simulation of mixing at the boundary between two compressible gases (of different densities) moving with a tangential velocity shear in the field of strong external acceleration are described. The simulation was performed using the well-known method of large particles for a two-dimensional case. The reliability of calculation results is supported by their comparison with analytical calculations, results obtained from the numerical solution of a similar problem, and experimental data.
