摘要：

In the present study, the vertical channel is divided into two regions one region is filled with Micropolar fluid and the other region is filled with viscous fluid. The channel is subjected to the transverse magnetic field. The coupled governing equations are solved subjected to the boundary conditions proposed by the previous authors using Finite Element Method (FEM). The results are compared with those computed by Kumar et al (2010). It is found that the increase in the magnetic field reduces the micro rotation (N) and velocity and enhances the temperature. Increase in the Eckert number (Ec), decreases the velocity, temperature and micro rotation. The Nusselt number and shear stress values are also analyzed.
