In a Triangular Duct Filled with Porous Material, Convection Heat Transfer is Experimentally Investigated

ABSTRACT

The current study conducts an experimental investigation of porous media. The packed duct is 1.5 m in length and has a diameter of 0.2 m. It is filled with porous meduim composed of glass bed of three different sizes (5 mm, 12.21 and 15 mm). (0.5,0.6, and 0.7) are the corresponding porosity values for the channel. This study investigates how changes in porosity and Reynolds number affect local Nusselt number and increased heat transfer coefficient. Using a porous construction, as opposed to an empty duct, increased the convection coefficient (hx) considerably by (84.2%, 86.2% and 88.18%) at porosity (0.5,0.6, and 0.7), respectively. The outcomes also showed that the local Nusselt number reduced as the air velocity rose and the flow's axial increased. As the air velocity grew. As a result, Re number rises with the diameter of glass spheres while the drag coefficient falls. When the findings of the present study were compared to those of earlier studies, they were satisfactory. The Nusselt number and the Reynolds number have established correlational links.
