Passive cooling is a method of dissipating heat rejected by electronic devices, and when associated to a phase change can be very effective. Phase change materials (PCMs) are widely used for thermal storage applications due to their ability to store and release large amounts of ...
Nanofluids are used to improve the thermal conductivity of heat transfer fluids. This study examined the effects on thermal conductivity of zinc oxide (ZnO)/ethylene glycol + water nanofluids as increasing concentrations of ZnO nanopartilces were added to the solution. A Thermal Constants Analyzer (TPS) measured ...
Phase change materials (PCMs) are substances that release large amounts of energy in the form of latent heat when they freeze. Paraffin waxes have many of the desired characteristics PCMs exhibit except that they have low thermal conductivity. In this experiment, Alumina and Carbon Black ...
Some researchers argue that the anomalous k enhancement data, for nanofluids, is caused by inaccuracies of thermal measurement methods. In this paper, measurements on thermal conductivities of nanofluid mixtures (alumina/water) by means of two different methods are accomplished. The thermal conductivity was measured, and ...
This article looks at the thermal properties of titanium oxide (TiO2) based nanofluids and their applications as thermal vectors. The nanoparticle size was studied by dynamic light scattering (DLS) and the stability was measured by Zeta potential. The concentrations of TiO2 used ranged from 1 to 35% ...
