Abstract

This research presents a numerical study of laminar flow characteristics and thermal enhancement in a channel partially occupied by a porous medium. Computational simulations were carried out using ANSYS Fluent to examine the influence of particle diameter and viscous resistance on key thermal performance indicators, including the Nusselt number, pressure drop, and overall performance index, within a two-dimensional configuration. The porous structure was intentionally incorporated into the channel to improve heat transfer behavior. The permeability of the porous medium was determined using the Kozeny–Carman equation, and simulations were conducted for various Reynolds numbers and particle sizes. The results indicate that increasing particle diameter enhances heat transfer performance, whereas higher viscous resistance significantly increases pressure losses in the channel. At constant porosity, the Reynolds number exhibits minimal impact on the overall performance index. The findings confirm that porous materials can effectively augment heat transfer efficiency; however, excessive viscous resistance may adversely affect overall system performance.
