The self-sustained oscillation of a circular jet coupled with a whistler nozzle has been investigated experimentally for a range of the controlling parameters, viz. , nozzle length, collar length, step height, and jet speed. It is shown that these parameters are related through an empirical formula which can be used to predict pure-tone frequencies at which a whistler nozzle can induce controlled excitation of a circular jet.
