Abstract
An experimental study was conducted to determine whether annular counterflow could be used to enhance mixing in high-speed subsonic and supersonic jets. Suction was applied to a collar placed concentrically about the main jet nozzle to establish a reverse flowing stream around the jet periphery. The main jet was operated at exit Mach numbers between 0.4 and 2, for stagnation temperatures from 20°C to 400°C. The results indicate that moderate levels of counterflow can be effectively used to enhance jet mixing under realistic operating conditions. Furthermore, the data suggest that the counterflowing technique becomes more effective as the jet temperature is increased.
