Stress-Work and Chemical Reaction Effects on MHD Forced Convection Heat and Mass Transfer Slip-Flow towards a Convectively Heated Plate in a Non-Darcian Porous Medium with Surface Mass-Flux

Abstract

Analysis is conducted numerically on forced-convective heat and reactive solute mass transfer of a steady incompressible, electrically conducting, chemically reacting and Joule dissipating viscous fluid streaming towards a stationary porous planar surface embedded in a saturated non-Darcian porous medium in the presence of surface mass flux, pressure stress-work and velocity slip. The governing coupled nonlinear boundary layer partial differential equations are transformed by existing similarity variables into a set of nonlinear, ordinary differentialequations in conjunction with the accompanying boundary conditions and then solved using a shooting quadrature along with fourth order Runge-Kutta integration scheme. The features of the flow, heat and mass transfer characteristics as per the skin friction coefficient, heat and mass transfer rates subject to simulated values of the Darcian number, Forchheimer number, Prandtl number, Eckert number, Schmidt number, reaction rate and order, mass flux (transpiration) and Biot number are analysed and discussed by means of tables while the dimensionless temperature, velocity and concentration profiles are captured through graphs. All these basic flow parameters bear significant influences on the flow.
