A nano-fluid was prepared by dispersing 0.1 wt% TiO2 nano particles in water along with a small amount of surfactant. The performance of the nano-fluid vis-a-vis water as coolant was studied on hot steel plates by measuring the cooling curves and by appropriate metallographic investigations. Significant enhancement in cooling rate was observed for the nano-fluid which could be due to an enhancement of convective heat transfer by jet impingement, coupled with lower surface tension of the nano-fluid, as compared to water.
