Full TextAbstract
The present study focuses on the analysis of two-dimensional Magnetohydrodynamic(MHD) flow past a circular cylinder wrapped with a porous layer in different laminar flow regimes. The Darcy-Brinkman- Forchheimer model has been used for simulating flow in porous medium using finite volume based software,Fluent6.3.In order to analyze the MHD flow, the mean and instantaneous drag and lift coefficients and stream patterns are computed to elucidate the role of Stuart number, N and Darcy number,Da. It is revealed that the magnetic fields are capable to stabilize flow and suppress the vortex shedding of vortices.The N-Replane shows the curves for separating steady and periodic flow regimes, Ncr and disappearing of vortex, Ndiss. For validate the solution,the obtained CD and St are compared with available results of literature.
