FIN ANALYSIS FOR HEAT TRANSFER RATE AUGMENTATION OF AIR COOLED IC ENGINE

Mechanical Engineering

Heat dissipation is probably one of the most important considerations in engine design. An internal combustion engine creates enough heat to destroy itself. Without an efficient cooling system, we would not have the vehicles we do today. The original radiators were simple networks of round copper or brass tubes that had water flowing through them by convection. Engine life and effectiveness can be improved with effective cooling. The cooling mechanism of the air cooled engine is mostly dependent on the fin design of the cylinder head and block. Insufficient removal of heat from engine will lead to high thermal stresses and lower engine efficiency. The cooling fins allow the wind and air to move the heat away from the engine. Low rate of heat transfer through cooling fins is the main problem in this type of cooling. The main of aim of this work is to study various researches done in past to improve heat transfer rate of cooling fins by changing cylinder block fin geometry and climate condition. Based on the research done, a model is selected to perform heat transfer analysis and identify possible increase in the rate by changing the fin profile. To perform the study, virtual simulation by CFD approach is proposed.
