Some liquid flows in weak acoustic field

The influence of acoustic vibrations on convective liquid flow is considered. In closed rectangular cavity for Prandtl number equal 0.01 in case of inclined and vertical vibrations the influence of vibration intensivity on flow structure is studied. It is shown that for acoustic cross vibrations of plane horizontal liquid layer with lengthwise gradient of temperature some flat-parallel convective flow is generated in this layer. The stability of this flow to flat perturbations is considered.
