A PROBLEM OF A VISCOELASTIC MAGNETOHYDRODYNAMIC FLUCTUATING-BOUNDARY-LAYER FLOW PAST AN INFINITE POROUS PLATE

In this work we study the motion of a two-dimensional incompressible flow of an electrically conducting viscoelastic fluid past an infinite porous flat plate subject to uniform suction in the presence of a transverse uniform magnetic field. The effects of the flow on the temperature of the plate are studied when the plate is thermally insulated, and when it is kept at a constant temperature that is higher than that of the free stream. A method proposed by Lighthill and Stuart is utilized in solving the problem. The effects of various parameters such as the magnetic number, the viscoelastic parameter. and the frequency of the free-stream oscillations on the flow are studied.
