Internal combustion engines at best can transform about 25 to 35percent of the chemical energy in the fuel into mechanical energy. About 35% ofthe heat generated is lost to the cooling medium, remainder being dissipatedthrough exhaust and lubricating oil.During the process of combustion the cylinder gas temperature often reaches quitea high value. A considerable amount of heat is transferred to the walls of thecombustion chamber. Therefore it Is necessary to provide proper coolingespecially to the walls of the combustion chamber. Due to the prevailing hightemperature, chemical and physical changes in the lubricating oil may also beoccurs this causes wear and sticking of the piston rings, scoring of cylinder wallsor seizure of the piston. Excessive cylinder wall temperature will therefore causethe rise in the operating temperature of the piston head. This in turn will affect thestrength of piston.In view of the above, the heat that is transferred into the wall of the combustionchamber Is continuously removed by employing cooling system. For coolingpurpose normally we are using air and water as cooling media. Here we areanalyzing this system by using CFD analysis with different Nano fluids such asaluminum oxide, silicon oxide, titanium Carbide & titanium nitride, at differentvolume fractions (0.2 & 0.3).Here we are doing Fluid flow analysis to determine the temperature, heat transfercoefficient, mass flow rate and heat transfer rate.
