Experimental performance evalution of heat transfer rate in automotive radiator by adding nanoparticles in different proportions

Abstract

CNG converted engines produces much more heat than Petrol or Diesel Engines .This is because the compression ratio of CNG is higher than other types of engines, high combustion temperature & low performance of coolants. Overheating can cause the engine failure sometimes. In our project we try to find out heat transfer rate of petrol engine & CNG engine and also compare between those engines. After comparing we find out CNG engine generate higher combustion temperature. Our goal is to find the heat transfer rate of the engine radiator using nanoparticle in different proportions. This will show that heat transfer rate increases as percentage of nanoparticle increases. From this we would be able to find that nanoparticle (Al2O3) with water as coolant may reduce use of materials in the radiator and reduce it’s cost.
