Abstract

Convective heat transfer in a differentially heated shallow rectangular enclosure due to the vibration of a vertical side wall is investigated numerically. The frequency of the wall vibration is chosen such that an acoustic standing wave forms in the enclosure. The fully compressible form of the Navier-Stokes equations is considered and an explicit time-marching algorithm is used to explicitly track the acoustic waves. Numerical solutions are obtained by employing a highly accurate flux corrected transport (FCT) algorithm. The steady second order flow structures, namely acoustic streaming, are found to be more significant than the primary oscillatory flow field on the cooling rates. The model developed can be used for the analysis of flow and temperature fields driven by acoustic transducers.
