Adaptive power supply unit: A solution for efficient 4G macro-cell base station
Experimental study of using both ZnO/ water nanofluid and phase change material (PCM) in photovoltaic thermal systems
In this study, the effects of simultaneous use of a ZnO/water nanofluid and a phase change material (PCM) as coolant mediums for a photovoltaic (PV) fluid/nanofluid based collector system are investigated experimentally. By designing and fabricating...
Experimental study on the effect of Zirconia nanoparticles on solidification heat transfer characteristics: A comparison with Titania nanoparticles
apparatus based on the compression refrigeration cycle has been used to ex- plore the solidification behavior of nanofluids as phase change materials. The experimental results show that ZrO 2 and TiO 2 nanoparticles considerably reduce the solidification...
Heat transfer enhancement in solidification process by change of fins arrangements in a heat exchanger containing phase-change materials
The ultimate model reduced solidification time up to 21.1 per cent of the Reference model which is a substantial improvement. Moreover, after testing different arrangements of rectangular fins and studying the flow pattern ...
Improving heat transfer in triplex tube heat exchanger containing phase-change materials by modifications of length and position of fins
attention from researchers due to its high
thermal energy density and constant operating temperature. This study numerically investigates the
melting process in a triplex tube heat exchanger containing phase change material -PCM- RT82. A...
Numerical study of the effects of nanofluids and phase-change materials in photovoltaic thermal (PVT) systems
In this paper, the effects of pure water, SiO2/water nanofluid, and a phase-change material (PCM) as coolants on the performance of a photovoltaic thermal (PVT) system are numerically investigated. The simulations are performed on two modules of PVT...
