Abstract
The tribological effects of nanofluids, the suspensions of nanoparticles in ordinary coolants, on heat-exchanger materials are largely unknown. Previous research explored wear on heat-exchanger materials from distilled-water-base nanofluids only, while most engine-coolants are alcohol solutions in water. In this research work the authors tested of aluminum and copper by jet impingement of 50%-ethylene-glycol in water solution and of its 2%-alumina nanofluid. The observed modifications showed that such nanofluid led to wear patterns that were different than those obtained with the base-fluid. Same tests also were performed with distilled water and its nanofluid as references. The results suggests that nanopowders can substantially enhance wear by decreasing the anticorrosion action of ethylene glycol by a synergetic mechanism of erosion-corrosion.
