Abstract

""\\"A solution to obtain efficient cooling systems is represented by the use of confined or unconfined impinging jets. Moreover,. the possibility of improving the thermal performances of the working fluids can be taken into account and the introduction of. nanoparticles in a base fluid can be considered. In this paper, a numerical investigation on confined impinging slot jet working. with a mixture of water and Al2O3 nanoparticles is described. The flow is laminar and a uniform temperature is applied on the. target surface. The single-phase model approach has been adopted. Different geometric ratios, particle volume concentrations, and. Reynolds numbers have been considered in order to study the behaviour of the systemin terms of average and localNusselt number,. convective heat transfer coefficient and required pumping power profiles, temperature fields, and stream function contours.\\"""
