| Abstract: | The nonstationary interaction between a supersonic pulse jet and a flat plate perpendicular to the jet axis is studied experimentally
and numerically. The time dependences of the pressure and heat flux at various points on the obstacle and the spatial distribution
of the density are obtained experimentally. The nonstationary flow is calculated numerically by the Godunov method. The experiments
and calculations reveal the effect of the reflected starting shock wave and the front part of the swirled gas outflow on the
distribution of the dynamic and thermal loads acting on the plate, in both time and space.
