HYDROMAGNETIC FLOW DUE TO NON-TORSIONAL OSCILLATIONS OF A DISC IN A ROTATING FLUID

K C BALAN

Abstract


The viscous flow due to non-torsional oscillations of a disc in a rotating system is studied when a uniform magnetic field is applied along the axis of rotation. The solution in the resonant case is obtained by using the initial value formulation. The solution for the steady motion due to uniform impulsive motion of the disc is  discussed. The expression for the depth of penetration of vorticity is obtained and the effect of magnetic field on it is also discussed.

Keywords


Non-torsional oscillations; Penetration of vorticity; Hydromagnetic flow.
