Abstract
Abstract:
Recent developments in automotive industry tend reseachers to design engines of lower volumes and higher efficiencies. Volume reduction enhances the generated heat per volume which in turn requires effective cooling methods to avoid thermal stresses on the engine walls. Nowadays nanofluids are extensively welcomed and employed as effective working fluids with efficient cooling potentials.
Boiling phenomenon, by providing more amounts of heat transfer in comparison with single-phase, provides conditions for size reduction. In the present study effects of adding nanoparticles to the pure water as the cooling working fluid in the radiator is assessed. The employed nanoparticle is TiO2. A 3D model of engine with the cooling passages is simulated by CFD both for the pure fluid (water) and nanofluid. It will be shown employing 1 vol% TiO2 nanofluid improves cooling heat transfer up to 37% in comparison with the pure water.
