Abstract

The backflow formation under gas outflow from the supersonic nozzle into vacuum was studied in detail both experimentally and numerically. Possibilities of backflow control (minimization) by using the gas-dynamic protective devices (screens) mounted at the nozzle outlet were discussed. It was shown that certain screen configurations can increase the backflow instead of decreasing it.
