Experimental and Numerical Analysis on Heat Transfer Characteristics of Shoe Brush-Shaped Fins

Experiments were on a shoe-brush-shaped fin consisting of a single bunch of splayed metal wires of circular cross-section from copper base plate. The fin was fabricated and its heat transfer characteristics were studied through experiments and numerical simulation. Fabrication was done through sand casting and the product was machined for required dimensions and surface finish. Numerical studies were done using ANSYS Fluent 3D. It can be inferred from the experiments and numerical studies that the fabricated fin maintains a lower base plate temperature than the rectangular flat fin and cylindrical pin fin for the same heat transfer rate, material and exposed area.
