abstract

In this study the flow field and heat transfer properties of a steady, two-dimensional flow field in a porous domain between two parallel plates is investigated numerically by using a discretized numeric code. Analysis has been carried for Reynolds number based on particle sizes ranging from 60 to 1000. Numerical results are compared with different numerical methods used for predicting this kind of flow. Results are obtained for different regime, various Rep numbers and the effect of Particles size is also investigated. Solutions indicate that by increasing the Rep , the flow in the porous media remains laminar where the flow has turbulence characteristics for Rep <50. Moreover, by increasing Rep , the value of average Nusselt number increases. Also, reducing the particle size affects the Nusselt number and it increases while the porosity remains the same.
