Abstract:

In general, analysis is made on any fluid considering it as a Newtonian fluid. Therefore there is a large variation between theoretical and practical results. In this paper, behavior of a micro-polar fluid which is a non-Newtonian fluid is presented by introducing different terms in navier-stokes and energy equations which exactly govern the flow of fluid. The micro-polar fluid considered is used as a coolant in the plate-type heat exchangers where hot fluid flows on one side and micro-polar fluid flows on the other side. Magnetic field is applied perpendicular to the direction of motion of fluid which contributes to the rotation of fluid particles there by reducing the shear stress. Hence effective heat transfer takes place in the hydrodynamic boundary layer requiring low pumping power and mass flow rate.
