Experimental Study on Effect of Nano ZnO on the Cooling Performance of Motorcycle Radiator

An internal combustion engine requires a proper cooling system to release heat from the engine. The working fluid or coolant in water-cooled impacts overall radiator performance. Several studies show that nanopowder can increase thermal performance of base fluids, although pressure drops significantly. This paper describes experimental study motorcycle using ZnO with distilled water and commercial as fluids. began by measuring boiling point specific (distilled coolant) nanofluids. Then, flow rate was measured function engine’s rotation speed. results all nanofluids increases highest achieved 0.5% – coolant, i.e., 110.06°C. Thus, will keep liquid phase lower fluid's heat. lowest is nanofluid coolant. Low relates higher temperature drops. Nanofluid has drop. Unfortunately, also drop approximately twice fluid. gives transfer coefficient than other fluid, 42.7 W/m2.°C when its 44.2 ml/s.
