Investigation of the effect of an acoustic field on the flow regime of a microjet

Abstract

Abstract A detailed visual study of the structure of a circular laminar micro-jet flowing into the atmosphere under the influence of an acoustic field was carried out. A jet of air flowed out of the profiled glass nozzle with a diameter of 500 microns. Characteristic vortex and coherent structures and zones with intense turbulent mixing were found in the flow. The features of the formation of vortex structures in a laminar jet under the influence of the acoustic field and the vibrational-rotational flow regime in the jet at the outlet of the nozzle were identified.
