Mixed convection flow over non-Darcy porous stretching/shrinking sheet

Abstract

An investigation has been carried out on heat and mass transport phenomena for mixed-convection flow over a vertically non-Darcy Forchheimer porous stretching/shrinking sheet considering the Soret - Dufour effects. With consideration of the appropriate similarity framework, the fundamental governing flow equations are converted into a system of non-dimensional equations. The bvp4c, a built-in solver of MATLAB software, is utilized to compute the numerical results of the flow problem. The present model is validated with previously published literature. The impacts of several related flow parameters on velocity, temperature, and concentration profiles have been displayed graphically. Also, the mass and heat transfer rates along with the coefficients of skin friction are calculated and discussed numerically. It is found that an increment in the thermal radiation parameter increases the fluid temperature, and the concentration gradient boosts up for the enhancement of the Soret number.
