DIRECT SIMULATION OF THE RELAXATION OF SEVERAL PARTICLES BEHIND TRANSMITTED SHOCK WAVES

The interaction of a shock wave with a system of relaxing particles was simulated numerically. A detailed wave pattern of the nonstationary interaction of a transmitted shock wave with moving particles has been obtained. The computational technique has been verified by the experimental data on the dynamics of particles behind the shock wave. It has been shown that the approximate model of calculating velocity relaxations is not effective in the case of mutual influence of particles when some particles are in the wind shadow of other particles.
