Effect Of Nozzle Size On Screech Noise Elimination From Swirling Underexpanded Jets

Abstract

The effect of nozzle size on screech noise elimination from swirling underexpanded jets is discussed. The screech tone was a result of the interaction between the quasi-periodic shock cell structure and the instability wave initiated at the nozzle lip. It was found that imparting swirling motion to the jet fluid would help eliminate such noises by creating fluid recirculation, by eliminating the shock cell structure or by reducing the number of shock cells. The swirling motion creates shear in the tangential direction in addition to that existing in non-swirling jets.
