• EFFECT OF THERMOPHORESIS AND HALL EFFECTS ON UNSTEADY MHD CONVECTIVE HEAT AND MASS TRANSFER FLOW OF A VISCOUS ROTATING FLUID PAST A STRETCHING SURFACE WITH THERMAL RADIATION, THERMO-DIFFUSION, RADIATION ABSORPTION IN PRESENCE OF NON-UNIFORM HEAT SOURCE

Abstract


To the author knowledge no studies have been made to analyze the combined influence of thermo-diffusion and radiation absorption effects on unsteady heat and mass transfer flow of a viscous incompressible electrically conducting fluid over a stretching sheet with thermal radiation, non-uniform heat source/sink and thermophoresis particle deposition. Hence, this problem is addressed in this paper. The conservation of mass, momentum, energy and diffusion equations were transformed into a two-point boundary value problem. In this article, we employ an extensively validation, highly efficient, variational finite-element method to study the effect of unsteadiness on heat and mass transfer flow past a semi-infinite stretching sheet. The problem presented here has many practical applications, such as, technological, manufacturing industries. MHD generators, plasma studies, nuclear reactors, geothermal energy extractions and polymer extrusion. Non-linear stretching velocity, surface temperature and surface concentration are considered in the present paper. The nonlinearity of the basic equations are additional mathematical difficulties associated with it, have led to the use of numerical method.
