Radiation and Diffusion Thermo Effects of Visco-Elastic Fluid Past a Porous Surface in the Presence of Magnetic Field and Chemical Reaction with Heat Source

Abstract

<jats:p>An analysis of two dimensional free convective hydro-magnetic flow of an electrically conducting visco-elastic fluid past a vertical porous surface has been studied in the presence of magnetic field and chemical reaction of first order with heat source. Simultaneously effects of heat and mass transfer are also studied in combination of the physics of diffusion thermo (Dufour effect) and suction at the plate is assumed to be constant. The equations governing are solved by perturbation technique. Analytical expressions for velocity, temperature and concentration fields, non-dimensional skin friction coefficient and Nusselt number are obtained. The results are analyzed graphically for various values of visco-elastic parameter along with a combination of other flow parameters involved in the solution.</jats:p>

“…Since the use of magnetic field can influence the heat generation/absorption process in electrically conducting fluid flows, the rate of cooling in many metallurgical processes and consequently the desired properties of the end product can be controlled. Furthermore, the influence of magnetic field on boundary layer flows has brought about its application in geothermal energy recovery, oil extraction and thermal insulations [16][17][18][19][20][21][22][23][24][25][26][27][28][29][30].…”
