Experimental Study of Heat Transfer Enhancement of Automobile Radiator using nano fluid as a Coolant with AL2O3 nano particles and Water as a base fluid.

Mechanical Engineering

Traditionally forced convection heat transfer in a car radiator was performed to cool water-containing circulating fluid. In this paper, the heat transfer performance of water has been compared with their binary mixtures. The radiator's upright tubes are filled with pure water and nanofluid. Different % of Al2O3 nanoparticle have been mixed with the base fluid (H2O) and its effect on the heat transfer performance of the car radiator have been found experimentally. Liquid flow rates from 10, 12, 14, 16 liter per minute and the fluid inlet temperature has been changed from 40o C to 70o C for the experiment. Utilizing the results of the experiments, the effectiveness, and overall heat transfer coefficients, U, were calculated. At various inlet temperatures and concentrations, overall heat transfer coefficients, U, were calculated. Heat transfer by nanofluids is clearly enhanced compared to base fluid i.e water, as demonstrated by the results. The best conditions result in a 0.4% increase in heat transfer compared with base fluids.
