MHD Flow, Heat and Mass Transfer about a Horizontal Cylinder in Porous Medium

Abstract

MHD flow, heat and mass transfer through porous media have seen a tremendous increase in research attention. This rapidly increasing research activity has been due to the increasing number of practical applications on porous media in chemical reactors, the underground spread of pollutant, many modern industries ranging from micro to macro and many other heat transfer processes. The problem of flow, heat and mass transfer about a horizontal circular cylinder in porous medium is considered in this study. Governing boundary layer equations are first transformed into ordinary differential equations and are solved by using Matlab's built in solver bvp4c. Velocity, temperature and concentration profiles are shown graphically for different values of parameters involved in the dimensionless equations and discussed in detail.

Analysis of MHD Forced Convective Flow of Variable Fluid Properties over a Saturated Porous Medium with Thermal Radiation Effect

“…Non-darcy unsteady mixed convection flow near the stagnation point on a heated vertical surface embedded in a porous medium with thermal radiation and variable viscosity was investigated by Hassanien [22]. Recently, Sharma [23] delved into the problem of MHD flow, heat and mass transfer about a horizontal cylinder in a saturated porous medium. The previous investigations on the field of MHD flow provide some clarifications and insights in understanding several pertinent aspects of modeling of transport phenomena in porous media but without combined effects of variable viscosity and thermal conductivity in the presence of thermal radiation.…”
