Abstract :

In this paper we have examined the effect of thermal radiation, heat generation/absorption, variable electric conductivity, variable surface temperature and variable concentration with variable viscosity on heat and mass transfer flow of micropolar fluid past a linear stretching sheet in a porous medium. In this problem the governing partial differential equations are highly non-linear which have been converted into ordinary differential equations by using the similarity transformations and then solved numerically by Shooting technique along with the Runge-Kutta numerical integration with appropriate boundary conditions. The effects of various pertinent non-dimensional governing parameters involved in the problem like , , , , , , , , have been studied on velocity, microrotation, temperature and concentratiuon and discussed through graphs. The physical parameters like local skin-friction coefficient, rate of coupling, surface heat transfer coefficient and surface deposition flux which are very important for engineering interest are also presented for distinct non-dimensional parameters in graphic and discussed their physical interpretation. The results in the paper are found for micropolar liquid fluids. The results of the present paper are compared with earlier studied work and found a close agreement between the results, hence an encouragement for the use of the present code for our problem.
