Opis

The tractor engine radiator cooling is enhanced by the nanofluid mechanism of heat transfer for its improved performance in Agricultural work. In this research work different amounts of Al2O3, CuO, Cu Nano particles have been added into water and Ethylene Glycol based fluids and its effect on the heat transfer performance of the radiator will be analysed. The experimental results show that a nanofluid in all concentration from 0.025 to 0.075 has enhanced thermal conductivity than pure water. The results also show that there is increased thermal performance compared to water based Al2O3 and CuO due to the higher density of ethylene glycol which favours for the increased heat transfer.When comparing the three different Nano fluids with same concentration the Cu/ethylene glycol has enhanced heat transfer coefficient due to the higher viscosity and density of the base fluid ethylene glycol. This is due to the increased Brownian motion of the nanoparticle while passing through the heat exchangers.
