Abstract: 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.
