The effect of adding phase change material (PCM) thermal conductivity into the building envelope has been demonstrated to contribute to enhancement of ...
Even though aluminum thermal conductivity is much higher than HDPE and mild steel, its influence on the performance of TES system is very low due to the very high internal heat resistance of PCM material stored in the spherical capsules.
The PCM considered for the experimental work is n-eicosane. The fins of a thickness of 2 mm and stem having a diameter of 5 mm are placed for the purpose of thermal conductivity enhancement. Experiments are conducted on all heat sinks with a constant fill ratio of 99%, and charging and...
The results show that the PCM thermal conductivity is significantly enhanced by the addition of graphene nanoparticles with a high aspect ratio. The addition of only 1%wt doubled the solid phase PCM thermal conductivity and for a 6%wt load the thermal conductivity increased by a factor of 3.5....
Experimental thermal conductivity of ethylene glycol and water mixture based low volume concentration of Al2O3 and CuO nanofluids Thermal conductivity of ethylene glycol and water mixture based Al2O3 and CuO nanofluids has been estimated experimentally at different volume concentratio......
of temperatures of the storage zone, surface zone, ambient, inlet and outlet of the internal heat exchanger have been measured and analyzed for ponds. It was shown the assisted PCM pond decreases the temperature difference between night and day. In addition, the pond had more thermal stability ...

Consequently, materials that boost thermal conductivity, like porous metal foams (specifically, aluminum foam with 20 PPIs and 0.88 porosity), geometry modifications, and dispersion of nano-sized powders (specifically, MWCNT-0.04) into paraffin (specifically, RT82), have been utilized in PCM-based ...
The transient performance of a phase change material (PCM)-based heat sink may be affected by its inclination angle because natural convection usually occurs and dominates melting during the operation of the heat sink. An experimental setup was designed and used in this study that allows for the...
