Investigation of an ejector scheme for forming heterogeneous supersonic flows under cold gas-dynamic spraying conditions

Thermophysics and Aeromechanics Aims and scope

Abstract

An ejector scheme intended for forming supersonic heterogeneous flows is experimentally examined as applied to conditions typical of cold gas-dynamic spraying. Pressure and temperature distributions in the supersonic part of the nozzle are reported, and critical operating regimes of the nozzle are identified. Specific features and advantages demonstrated by this scheme in practical applications are considered. Results of preliminary tests on the application of coatings with the use of the nozzle unit under study are presented.
