Visualization methods in developments of power axisymmetric nozzle

Abstract eng:
In this paper research results of axi-symmetric, actively controlled fluidic nozzle are presented. Jet visualization was performed in a horizontal plane passing through the nozzle symmetry axis by means of smoke-wire visualization technique, when “a smoke” (in fact an aerosol) is generated on a resistance wire. The wire was located perpendicular to the nozzle axis. There have also been presented results obtained using the method of dynamic visualization, PIV method, and visualization of the nozzle thermodynamic properties.
