NUMERICAL APPROACH TO THERMO-CONVECTIVE MICRO-POLAR FLUID WITH RADIATION IN PERMEABLE MEDIUM.

A steady, incompressible, and thermo-convective flow of micro-polar fluid over a stretching permeable sheet with heat and mass transfer under effects of radiation, Soret, Schmidt, and Dufour numbers have been analyzed. The modeled governing equations, of the classical Navier-Stokes, are coupled with micro rotation, temperature, and concentration equations, in the form of Partial Differential Equations, along with initial and boundary conditions, are transformed into a system of nonlinear coupled Ordinary Differential Equations by using an appropriate transformation. The numerical solution is obtained by using the Parametric Continuation Method. For the validity of the scheme, the results are compared with a numerical package bvp4c. It has been observed that both the results are in the best agreement with each other. The effects of associated parameters on the dimensionless velocity, micro-rotation, temperature, and concentration profiles are discussed and depicted graphically. It has been detected that the permeability parameter gives rise to the microrotation profile. [ABSTRACT FROM AUTHOR]
