Comparison of CFD Analysis of Heat Transfer Augmentation & Surface Heat Transfer Co-efficient of I. C. Engine Fins at Different wind Velocities with Experimental Investigation

Designing an I C Engine has a great emphasis on Heat Dissipation. The more heat dissipation causes more efficiency of the engine. Insufficient dissipation of heat causes high thermal stresses, which is responsible for lesser efficiency of an I C Engine, too. Modern vehicles could have such technological research due to better cooling systems of an engine. The conventional radiators were made of networks of round brass or copper tubes through which water was kept flawing. But in air cooled system, the main focus is on design of fin of cylinder head to get heat dissipated. I C Engine fins provide more surface area to the heat generated to get it dissipated in lesser time. Furthermore, fins allow the wind to flow over them and to het the heat away from the engine along with the flow of air. But, such cooling systems are not yet effective as the water cooled systems. So, more emphasis is given in this work to study the previous updated cooling systems which includes, changing the block of cylinder for various fin geometry and climate conditions. In this research work focus is given to compare the heat transfer co – efficient at different velocities analysed in CFD with Experimental investigated data.
