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.
