Sinopsis

We have experimentally investigated the heat transfer performance as provided by the use of a particular nanofluid, namely water-Al2O3 mixture, for a liquid system that is destined for cooling of electronic components. Measured data have clearly shown that the inclusion of nanoparticles within the saturated water has produced an appreciable enhancement of the cooling block convective heat transfer coefficient, which has been found to increase as much as 15% (for a particle concentration of 6.8%) with respect to that of the base fluid. Such enhancement becomes more important with an increase of the mass flow rate and the particle volume concentration. With an augmentation of the particle concentration, a clear decrease of the junction temperature between the heated component and its cooling block was also observed. A new correlation has been proposed for computing the Nusselt number for the ranges of parameters: 14000 ≥ Re ≥ 680, 9.5 ≥ Pr ≥ 4 and 6.8% ≥ φ ≥ 0.
