This document summarizes a project seminar on analyzing extended surfaces subjected to forced convection. The project aims to increase heat transfer rates using different fin geometries. The objectives are to study heat transfer characteristics of various fin designs, fabricate a test rig, and analyze efficiency and effectiveness. The methodology includes theoretical calculations, analytical and experimental analysis, and comparing results. Future work may include different materials, fin shapes, and applications like electronics cooling. The experimental setup includes a fan, thermocouples, test fins, duct, and heater with dimmerstat control. Specifications of components are provided.
