Experimental research and CFD analysis on engine fins with varied geometries

This study explores the thermal performance of engine fins with different geometries through both experimental investigation and computational fluid dynamics (CFD) analysis. Engine fins are essential for managing thermal stresses and temperature variations in automobile engines. By modifying the shapes of these fins, their heat dissipation efficiency can be improved. The experimental research involves testing engine fins made from various materials, including Aluminum Alloy, Grey Cast Iron, and Magnesium Alloy. For instance, Aluminum Alloy fins demonstrated a temperature range of 1436.2℃ to 1500℃ and a total heat flux range of 509.23 W/m² to 7.0404e5 W/m², depending on the fin geometry. Simultaneously, CFD simulations were performed to thoroughly analyze the fluid dynamics and heat transfer characteristics of different fin geometries. The integration of experimental results and CFD simulations provides valuable insights into the thermal efficiency of engine fins, contributing to the expansion of more effective cooling systems for automotive applications.
