Abstract

The study of heat and mass transfer of oscillatory casson flow inporous medium subject to an inclined magnetic field, radiative heatflux and heat source is presented. It is supposed that Casson fluid islittle conductive and produced emf is insignificant. The solutions ofcoupled partial differential equations of velocity, temperature and con-centration profiles are found using Galerkins technique of finite elementmethod. The effect of various parameters such as Reynolds number Re,Grashoff number Gr, Solute Grashoff number Gc, Peclet number Pe,Hartman number Ha, Scmidth number Sc, Permeability parameter K,Radiative parameter R, Heat generation parameter S, Chemical reactionparameter Kr and frequency parameter w on velocity, temperature andconcentration are shown graphically and skin friction, Nusselts numberand Sherwood number are discussed by tables.

Highlights

Fluid flow with heat and mass transfer in porous medium has many applications on geophysics, petro chemical engineering, oceanography, boundary layer control in aerodynamics and polymer technology
The effect of magnetic field and pressure gradient on velocity and temperature focused.[6]analyzed the MHD flow through parallel plates with heat and mass transfer and showed that Hartman number reduces the flow.[7] ascertained that Hatmann number enhances induced magnetic field and magnetic Reynolds number influenced velocity in their study of heat and mass transfer between vertical parallel plate.[8] investigated MHD Poiseulle flow between two parallel plates with heat transfer an showed that Hartmann number suppresses flow and Prandtle number subsides temperature profles.[9] discussed the steady Poiseuille flow between two infinite parallel plates in an inclined magnetic field and ascertained magnetic field reduces the velocity.[11] obtained the analytic solutions for velocity,temperature,concentration, skinfriction, heat and mass transfer using Laplace technique.[12] studied MHD free convective non-newtonian flow with variable permeability
Numerical solution of unsteady two dimensional hydromagnetic flow with heat and mass transfer of casson fluid discussed by [13].[14] given observation of unsteady MHD poiseuille flow between two infinite parallel plates with heat and mass transfer subjected to porous material and an inclined magnetic field.[15]discussed heat and mass transport on MHD free convective flow through porous medium past an infinite vertical plate.[16]shown the effect of an inclined magnetic field is to reduce flow of dusty fluid in unsteady case.[17] discussed effects of variable thermal conductivity and heat source/sink on MHD flow near a stagnation point on a boundary conditions.[18] highlighted the heat and mass transfer in steady flow in presence of an inclined magnetic field and found velocity first decreases and rises gradually
