CONVECTIVE HEAT-TRANSFER DUE TO ACOUSTIC STREAMING ACROSS THE ENDS OF A KUNDT TUBE

Convective heat transfer due to acoustic streaming across the ends of a tube supporting a standing sound wave is investigated. Analytical techniques are used along with the numerical solver PHOENICS for the solution of the complete elliptic form of the equations governing the steady transport due to the streaming motion. A parametric study of the effects of the controlling acoustic and geometric variables is conducted, and Nusselt number correlations are developed for air. The results obtained can be used in the thermal analysis of test cells for containerless processing of materials in space using acoustic levitation.
