Abstracts:

The results of experimental investigations of the round and plane microjet with a “top-hat” and parabolic velocity profile at the nozzle exit under the acoustic oscillations at low Reynolds numbers are presented. It was found that the microjet and macrojet transformed under the influence of the acoustic field. However, for the case of microjet the generation of vortex rings doesn’t occur and a new transformation mechanism of the round jet into the plane jet develops with sinusoidal instability, which is typical for the plane jets. The visualization pictures of a propane diffusion combustion in the microjet are showed, features of development of the instability under the convective forces are noted.
