Laminar Magnetohydrodynamic Boundary Layer on a Disk in the Presence of External Rotating Flow and Suction

Article

Abstract

The rotation of a conducting viscous medium near a dielectric disk in a homogeneous magnetic field in the presence of an external flow and a suction is considered. On the basis of the Dorodnitsyn transformation, an analytical solution of the system of boundary-layer and heat-conduction equations has been obtained. It is shown that the direction of the radial flow in the boundary layer of the disk can be changed by changing the ratio between the angular velocities of the external flow and the disk and the ratio between the temperatures in the external flow and on the disk as well as by varying the hydrodynamic Prandtl number. The influence of the magnetic field on the intensity of circulation of the viscous medium was investigated.
