VEERESH, S.V. K. VARMA & D. PRAVEENA Department of Mathematics, S. V. University, Tirupati, Andra Pradesh, India ABSTRACT Heat and Mass transfer propertieson MHD boundary layer flow of a viscous, incompressible, free convective, chemically reactive, radiative and electrically conducting fluid on a moving inclined heated porous plate in the presence of temperature dependent heat source and Joule heating is analyzed. The non-linear coupled partial differential equations are solved by regular perturbation technique. The impact of different pertinent parameters on velocity, temperature and concentration distribution have been studied and explored with the help of graphs. We observed that velocity decreases for increasing values magnetic parameter M where as it shows reverse effect in the case of permeability parameter K. But the presence of temperature dependant heat source has the mixed effect on the velocity and as well as on temeperature. The preence of the prandtl number and Schmidt number condences the thermal boundary layer and concentration boundary layer respectively.

INTRODUCTION The convective heat and mass transfer flows in an inclined porous plate find a number of applications in many branches of science and technology like chemical industry, cooling of nuclear reactors. MHD power generators, geothermal energy extractions processes, petroleum engineering etc. Convective heat and mass transfer flows in the presence of various physical properties for the cases of horizontal and vertical flat plates have been attracting the attention of many researchers now a days[1]–[17]. However, the boundary layer flows adjacent to inclined plates or wedges have received less attention. For the problem of coupled heat and mass transfer in MHD free convection, the effect of both viscous dissipation and Ohmic heating are not studied in the above investigations. However, it is more realistic to include these two effects to explore the impact of the magnetic field on the thermal transport in the boundary layer. With this awareness, the effect of Ohmic heating on the MHD free convection heat transfer has been examined for a Newtonian fluid by Hossain [18]. Hossain and Gorla [19] studied Joule heating effect on magnetohydrodynamic mixed convection boundary layer flow. To investigate the mixed convection flow of an electrically conducting and viscous incompressible fluid past an isothermal vertical surface with Joule heating in the presence of a uniform transverse magnetic field fixed relative to the surface. It was assumed that the electrical conductivity of the fluid varies linearly with the transverse velocity component. Beg et al. [20] solved magnetohydrodynamic Hartmann–Couette flow and heat transfer in a Darcian channel with Hall current, ionslip, viscous and Joule heating effects. In their study Reddy et al. Chen [21] studied the problem of combined heat and BEST: International Journal of Management, Information Technology and Engineering (BEST: IJMITE) ISSN (P): 2348-0513, ISSN (E): 2454-471X, Vol. 3, Issue 11, Nov 2015, 63-74 © BEST Journals
