Unsteady Free Convection and Mass Transfer Flow of Micropolar Fluid Embedded in a Porous Media
نویسندگان
چکیده
This paper deals with the unsteady free convection and mass transfer flow of micropolar fluid embedded in a porous media. The governing equations involve the fluid and micropolar velocities respectively, temperature and concentration fields. The effects of material parameters on the velocities, temperature and concentration are discussed. Perturbation method is used to obtain the solutions to the governing equations. Results show that the velocity increases with an increase in Grashof and modified Grashof numbers G and Gm respectively. While an increase in the Prandtl number Pr and Schmidt number Sc lead to a decrease in the temperature and the concentration respectively.
