The problem of motion dynamics of two particles in a supersonic flow behind an incident
shock wave was considered numerically and experimentally. The experiments were carried
out in a shock tube. High-speed shadowgraphy with a laser stroboscope light source was
used. The mathematical model was based on the two-dimensional Euler equations. The
original, highly scalable, parallel algorithm of the Cartesian grid method for simulation of
flows with shock waves in areas with changing geometry was used in the numerical …

The problem of motion dynamics of two particles in a supersonic flow behind a passing
shock wave is considered numerically and experimentally. The parallel Cartesian grid
method for simulation of flows in areas with changing geometry is used. The main stages of
the process are described from the point of view of the implemented shock-wave
configurations. The effect of changing two modes of supersonic flow around two particles is
obtained. The obtained flow patterns and dynamics of particle motion correspond to the …
