Abstract-This review examines the thermal analysis of engine cylinder fins with varying geometries, focusing on their critical role in heat dissipation for internal combustion engines. The study evaluates four distinct fin designs—angular, curved, rectangular, and cylindrical—using Computational Fluid Dynamics (CFD) analysis performed in Ansys Workbench. The research demonstrates that fin geometry significantly impacts cooling efficiency by influencing temperature distribution, airflow patterns, velocity profiles, and pressure distribution across the engine cylinder surface. The analysis reveals that curved fins exhibited superior thermal performance compared to traditional designs, achieving higher heat transfer coefficients and more effective cooling. This enhanced performance can be attributed to the curved geometry’s ability to create optimal turbulence patterns that maximize contact time between cooling air and fin surfaces. The findings highlight the importance of optimizing fin design beyond conventional rectangular geometries to improve thermal efficiency in air-cooled engines. This review synthesizes these results to provide insights for engineers and designers seeking to enhance engine cooling systems through geometric optimization rather than material substitution alone.
