Acoustic Streaming and Heat Transfer in a Rectangular Channel with Differently Heated Horizontal Walls

Abstract

Acoustic streaming and heat transfer in a vibrating rectangular two-dimensional channel filled with gas, the vertical walls of which are thermally insulated and the horizontal walls are maintained at different temperatures, are numerically investigated. The features of the wave motion of the gas are studied. The influence of the temperature difference of the walls, amplitude and frequency of vibration on acoustic streaming and the period average temperature is determined.
