Abstract:
In this paper, the MHD flow and heat transfer of an incompressible electrically conducting micropolar fluid through a parallel plate channel is investigated. A uniform magnetic field was applied perpendicular to the flow and, due to the fluid motion, a induced magnetic field appears along the lines of motion. The upper and lower plates have been kept at the two constant different temperatures and the plates are electrically insulated. Partial differential equations governing the flow, heat transfer, micro rotation and magnetic field conservation are transformed to ordinary differential equations and solved under physically appropriate boundary conditions. Solutions obtained for the velocity, micro-rotation, temperature and induced magnetic field in function of Hartmann number, the coupling parameter and the spin-gradient viscosity parameter are presented graphically.
