A numerical study on the enhancement of heat transfer by pressure distributions in acoustic fields

The enhancement of heat transfer in a cavity was investigated in the absence of and in the presence of acoustic streaming induced by ultrasonic waves. The present study provides the experimental and numerical results of heat transfer in the acoustic fields. The enhancement of heat transfer was experimentally investigated in the presence of acoustic streaming and was compared with the profiles of acoustic pressure calculated by the numerical analysis. A coupled finite element-boundary element method (FE-BEM) was applied for a numerical analysis. Experimental and numerical studies clearly show that pressure variations are closely related to the enhancement of heat transfer in the acoustic fields.
