MHD Boundary Layer Flow of Micropolar Fluids due to Porous Shrinking Surface with Viscous dissipation and Radiation

The mathematical analysis and numerical solution for the flow of micropolar fluids owing to shrinking boundary is considered in the presence of magnetic field and thermal radiation. The parametric study of the problem demonstrates the effects of magnetic field, suction, micropolar material parameter and thermal radiation on velocity, microrotation and temperature. The mathematical model of the problem is transformed to non-dimensional form to obtain numerical solution. The results have been obtained for several representative values of the material parameters d 1 , d 2 and d 3 , heat source parameter l and magnetic parameter M, suction/injection parameter S, Eckert number E c , Radiation parameter R n and Prandtl number P r . The flow speed and microrotation are slowed with incremented inputs of micropolar parameter d 1 . The fluid temperature increases with radiation parameter but it diminishes against suction.
