摘要

The effects of heat and mass transfer on free convective flow of micropolar fluid were studied over an infinite vertical porous plate in the presence of an inclined magnetic field with an angle of inclination α with a constant suction velocity and taking Hall current into account. The dimensionless governing equations are reduced to a system of linear differential equations, making use of a regular perturbation method, and equations are solved analytically. The control of various parameters on the flow is discussed graphically. This present study is of immediate interest in geophysical, medicine, biology, and all those processes that are greatly embellished by a strong magnetic field with a low density of the gas. The resultant velocity trim downs with increasing suction parameter and viscosity ratio, while it enhances with heat source parameter. The micro-rotational velocity rises with increasing Hall parameter. The temperature increases with increasing heat radiation parameter and reduces with suction parameter. Concentration diminishes with increasing chemical reaction parameter. The rate of heat transfer increase with Prandtl number and the rate of mass transfer enhances with the chemical reaction parameter.
