Natural Convection Heat and Mass Transfer of a Chemically Reacting Micropolar Fluid in a Vertical Double Passage Channel

J. Prathap Kumar | J.C. Umavathi | Jagtap Sharadkumar

Abstract: The problem of fully developed mixed convection for a laminar flow of a micropolar fluid in a vertical double passage channel has been investigated analytically. The channel is divided into two passages by means of a thin perfectly conductive plane baffle and the velocity, temperature and concentration will be individual in each streams. After inserting the baffle the fluid is concentrated in stream-I. The governing equations of the flow have been solved analytically subject to the relevant boundary and interface conditions. The closed form solutions are represented graphically. The effect of governing parameters namely, buoyancy ratio, vortex viscosity parameter and chemical reaction parameter on the velocity, microrotation velocity, temperature and concentration has been discussed. It is seen that increasing the vortex viscosity parameter tends to increase the magnitude of microrotation velocity and thus decreases the fluid velocity in the vertical channel. Moreover, the volume flow rate, the total heat rate added to the fluid and the total species rate added to the fluid for micropolar fluids are lower than those of Newtonian fluids.
