Analysis of the Effect of Fin Material on Temperature Distribution in Rectangular Cross-Sectional Straight Fins

The design of fins needs to be optimized to ensure effective heat transfer or dissipation from the engine to the surrounding air. The choice of material for the fins is crucial to facilitate unhindered heat dissipation from the fins to the environment. This study employed a numerical simulation using the finite difference method to analyze the temperature distribution within various sections of the fins. The calculations were performed from the transient state until a steady state was achieved. The findings indicate that the fin material significantly impacts the temperature distribution across different sections of the fin. Heat propagation in the fin is predominantly through conduction, thus the thermal conductivity of the material substantially affects the temperature distribution along the fin. Fins made from conductive materials exhibit higher temperature changes over time intervals and reach a steady state more rapidly. Conversely, fins made from less conductive materials fail to transfer heat efficiently to the fin's end, resulting in a higher temperature difference between the base and the tip and a longer time to reach a steady state.
