Application of Nanofluids in Engine Cooling System

This paper made use of the strengthening heat-transfer character of nanofluids and applied nanofluids to engine cooling system. CFD numerical simulation method was employed to analyze the application value of nanofluids in engine cooling. The simulation results indicated that nanofluids could enhance engine heat dissipating capacity and Cu-water nanofluids had better heat-transfer capability. It was also found that the more concentrated of the nanoparticles, the more enhanced of the engine heat dissipating capacity. When the concentration reached 5%, the heat dissipating capacity would increase by 44.1%. With a remarkable enhancement on heat-transfer capability, the workload of the pump of engine cooling system only increased by 6%, which could be acceptable.
