DESIGN AND THERMAL ANALYSIS OF IC ENGINE FINS WITH DIFFERENT CROSS-SECTIONAL FINS

Abstract

Cooling  fins  in  IC  engines  remove  excess  heat  from  it to  protect  its  components  from  thermal damages. These fins work on the principle of convection heat transfer. The cooling efficiency of the engine fins can   be improvised by changing geometry, thermal conductivity and the material of the cooling fins. Computational fluid dynamics is the technique used to determine thermal stresses and temperature distribution through the fins. CFD analysis gives accurate and realistic results in comparison with physical analysis processes. This project is based on designing more efficient cooling fins for a 150cc (Honda -Unicorn) bike engine by improvising the design and the material of the fin. Where the modeling of the fin is performed on Creo modeling software and the CFD analysis is performed on ANSYS 15.0 Workbench software.
