“…The investigation on nanofluid behaviour is becoming more and more popular, as testified by recent reviews and papers on this issue [35][36][37][38][39][40][41][42][43][44] but inconsistencies in published data and disagreements on the heat transfer mechanisms have been underlined by Keblinski et al [45] and recently by Gherasim et al [46]. However, a few examples of studies on nanofluids in impinging jets have been investigated experimentally and numerically and, according to the best knowledge of the present authors, their investigations have been reported in [46][47][48][49][50][51][52][53][54][55][56][57][58][59]. Roy et al [50] provided the first numerical results on the hydrodynamic and thermal fields of Al 2 O 3 /water nanofluid in a radial laminar flow cooling system, underlining a heat transfer enhancement up to 200% in the case of a nanofluid with 10% in nanoparticle volume concentration at a Reynolds number equal to 1200.…”

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 Al 2 O 3 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 system in terms of average and local Nusselt number, convective heat transfer coefficient and required pumping power profiles, temperature fields, and stream function contours.

Water and Ethylene Glycol (EG) blend is a kind of conventional heat transfer fluid, generally used in many energy systems, to retain the good heat transfer (heating or cooling) ability of water, as well as widening the operating temperature range. Further, the enhancement of thermo-physical properties of water/EG blend, by using nanoparticles would be very useful for the better performance of the energy systems. In the present study, alumina particles are used to prepare and determine the thermal conductivity and viscosity of Water and Ethylene Glycol (EG) blend based alumina nanofluid. It is observed that, the maximum augmentation occurs in the thermal conductivity is 11.37% at 1.6 Vol%, for water+EG based Al 2 O 3 nanofluids. It is also observed that, dynamic viscosity is increased by 10.36% by 1.6 Vol%, for (Water + EG) /Al 2 O 3 nanofluid compared to water + EG blend. Thermal conductivity and viscosity models for water + EG based Al 2 O 3 nanofluid, are proposed.
