MHD ON A CYLINDER IMPLANTED IN A POROUS MEDIA OF MICROPOLAR FLUID

This article handles MHD flow of micropolar fluid through a rigid cylindrical particle implanted in a porous media. Flow is considered to be uniform at a distance away from the cylinder. A uniform magnetic field is applied perpendicular to the flow direction. Motion in porous media is governed by Brinkman's equation. At the surface of cylinder, we assume no-slip of velocity components and no-spin of microrotational component. Exact solution for the problem is reported. Influence of Hartmann number, permeability and micropolarity parameters on the coefficient of drag and tangential velocity are discussed numerically. In deduction, various results of flow past impenetrable cylinder are obtained which are in good agreement with earlier published works.
