ABSTRACT

In the present work, a numerical analysis is performed to study fluid dynamics and heat transfer for flow over a cylinder embedded in a porous medium. The objective of the work is twofold: first, to address the effect of porous medium on von Karman vortex formation at the cylinder wake, where it is found that porous media may suppress the formation of the vortex for a certain range of controlling parameters; and, second, adding porous medium to the domain of interest (air) modifies the effective thermal conductivity by many fold, depending on the material of the porous medium. Hence, an increase in the rate of heat transfer is expected. The work tries to quantify the rate of heat transfer. In this work the effect of the Reynolds number, Darcy number, and thermal conductivity ratio on the flow separation and rate of heat transfer are introduced and discussed. The Prandtl number is fixed at 0.71 (air). It is found that the porous medium enhances the rate of heat transfer and the rate of enhancement is a strong function of the thermal conductivity ratio. A correlation is suggested for the rate of heat transfer (Nusselt number) as a function of the Reynolds number and effective thermal conductivity ratio for the range of the investigated Darcy numbers.
