The acoustic stream

Consider a plane standing sound wave that corresponds to the velocity field where . Let the characteristic (transverse) dimension of the problem be . The flow field just described corresponds to inviscid flow. However viscous effects will be important close to a solid wall; there then exists a boundary layer of thickness or, penetration depth . Rayleigh streaming is best visualized in the approximation As in , the velocity components are much less than . In addition, th… WebAcoustic streaming is forces by the action of a Reynolds stress, defined as the mean value of the acoustic momentum flux; but it is exclusively the dissipation of acoustic energy flux that permits gradients in momentum flux to force acoustic streaming motions (section 3). On the other hand, these do not tend to zero as a dissipation coefficient ...
