Effect Of Magnetic Field And Radiation On MHD Heat And Mass Transfer Of Micropolar Fluid Over Stretching Sheet With Soret And Dufour Effects

摘要

The influence of magnetic field and radiation on unsteady MHD boundary layer flow, heat and mass transfer analysis over a stretching sheet embedded in porous media filled with viscous micropolar fluid is numerically investigated. The governing conservation equations are converted into the set of ordinary differential equations and are solved numerically by using Finite element method. The influence of key non-dimensional parameters, namely, suction parameter, Magnetic parameter, Unsteadiness parameter, Eckert number, Soret parameter, Dufour parameter and Micro-rotation parameter on velocity, micro-rotation, temperature and concentration profiles are portrayed graphically. Furthermore, skin-friction coefficient, couple stress coefficient, rates of heat and mass transfer for various values of the governing parameters are calculated and the results are summarized in tabular form.
