Abstract

Double sideband suppressed carrier excitation is utilized to achieve modulated ultrasonic radiation pressure (MURP). MURP is shown to be an effective method to stimulate low-frequency drop production rates from large laminar liquid jets. The jet deformation oscillates and drops are generated at the frequency of the MURP and when the jet deformation is small its amplitude is experimentally found to be proportional to the radiation pressure amplitude; both are manifestations of the oscillating radiation pressure effect. The method was previously demonstrated for acoustically levitated drops
