Magnetic influence on the acoustic streaming boundary layer at a solid wall

Abstract

The effect of acoustic streaming generated due to a standing wave over a flat plate in the presence of a magnetic field has been discussed. Due to this unsteadiness, the flow is divided into two regions: the boundary layer region and the core flow region. Invoking successive approximation method, we found the velocity expression for the core region confirming that the velocity is independent of viscosity but depends on a magnetic field and is used to demonstrate the Couette flow.
