A numerical solution to the problem of mixed convective MHD chemically reacting flow past a vertical porous plate in the presence of thermal radiation and cross diffusion effects was studied. Instead of the commonly used conditions of constant surface temperature or constant heat flux, a convective boundary condition is employed which makes this study unique and the results more realistic and practically useful. The momentum, energy, and concentration equations derived as coupled second-order, ordinary differential equations and are solved numerically using a highly accurate and thoroughly tested finite element method. The effects of Grashof number (defined to represent a mixed convection parameter) for heat and mass transfer, Soret number, Dufour number, Viscous dissipation parameter, Chemical reaction parameter, Permeability parameter, Thermal radiation parameter and Biot number on the velocity, temperature and concentration profiles are illustrated and interpreted in physical terms. The present results agree closely with the existing results for the special cases of the problem. This close agreement lends support to the validity of the present analysis and the accuracy of the numerical computations. The paper also contains a table in which the data for the local skin friction, local Nusselt number and local Sherwood number are provided for various combination values of the parameters that govern the momentum, energy and concentration convey in the mixed boundary layer.

This study deals with the combined effects of Navier Slip, Convective cooling, variable viscosity, and suction/injection on the entropy generation rate in an unsteady flow of an incompressible viscous fluid flowing through a channel with permeable walls. The model equations for momentum and energy balance are solved numerically using semi-discretization finite difference techniques. Both the velocity and temperature profiles are obtained and utilized to compute the entropy generation number. The effects of key parameters on the fluid velocity, temperature, entropy generation rate and Bejan number are depicted graphically and analyzed in detail.

“…In convective boundary condition, heat is supplied to the convecting fluid through a bounding surface with a finite heat capacity, which provides a convective heat transfer coefficient. Makinde and Aziz [13] scrutinized hydro-magnetic mixed convection flow along a vertical plate embedded in a porous medium, with influence of convective boundary condition. In the presence of uniform magnetic field and thermal radiation, the stagnation point flow towards stretching plate in a micropolar fluid with slip velocity and convective boundary condition investigated by Mostafa et al [14].…”

Based on the nonlinear variation of density with temperature (NDT) in the buoyancy term, the mixed convection flow along a vertical plate of a micropolar fluid saturated porous medium is considered. In addition, the effect of homogeneous-heterogeneous reaction and convective boundary condition has been taken into account. Using lie scaling group transformations, the similarity representation is attained for the system of partial differential equations, prior to being solved by a spectral quasilinearization method. The results show that in the presence of aiding and opposing flow situations, both the species concentration and mass transfer rate decreases when the strength of homogeneous and heterogeneous reaction parameters are enhanced.
