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

Convective heat transfer due to acoustic streaming across the ends of a tube supporting a standing sound wave is investigated. Analytical te chniques are used along with the numerical solver PHOENICS for the sol ution of the complete elliptic form of the equations governing the ste ady transport due to the streaming motion. A parametric study of the e ffects of the controlling acoustic and geometric variables is conducte d, and Nusselt number correlations are developed for air. The results obtained can be used in the thermal analysis of test cells for contain erless processing of materials in space using acoustic levitation.
