Numerical study on the effect of linear/non-linearly stretching sheet with suction or injection of MHD mixed convection Jeffrey fluid flow in a vertical stagnation - point of a porous medium in the presence of thermal radiation and chemical reaction

摘要

The effects of linear /non-Linearly stretching sheet with MHD mixed convection Jeffrey fluid flow in a vertical stagnation-point of a porous medium is numerically studied. The influence of thermal radiation, chemical reaction and slip is also considered in this study. The partial momentum and energy equations are transformed into a set of ordinary differential equations by employing suitable similarity transformations and are solved numerically using the Runge-Kutta fourth order method in association with the shooting technique in MATLAB. The effects of Jeffrey parameter, suction/injection parameter, slip velocity parameter, linearity or non-linearity parameter, magnetic parameter, permeability parameter, velocity ratio parameter, Prandtl number, thermal radiation parameter, chemical reaction parameter and Eckert number on velocity, temperature and concentration profiles are presented graphically while the skin friction coefficient, the local Nusselt number and Sherwood number are represented numerically.
