Experimental Investigation of Automobile radiator using Tungsten trioxide Nano-fluid

Conventional fluids (ethylene glycol and H2O) heat transfer performance results to be poor when incorporated with an automobile radiator. An experimental study was performed to explore the enactment of automobile radiator using H2O and WO3 nanofluid as operational fluids. Analysis and comparison were carried out for the heat transfer rate and outlet temperature of fluid for various flow rate ranging from 0.2m3/hr to 0.5 m3/hr. Preperation of nanofluid was done for water with 0.0167%, 0.034% and 0.0667% volume concentration of WO3 nanoparticle. The inlet condition of fluid was set at 50°C as the impact for the variation of temperature conditions on system performance were minimal. On experimentation, the maximum increase in the heat transfer rate was by 4.18% on comparison with base fluid.
