Experimental Study of Paraffin Wax-Copper Nanoparticles Thermal Storage Material

Belen Zalma and et.al [3] conducted a review of the history of thermal energy storage with solidliquid phase changes.Three aspects materials, heat transfer, and applications which contain over 150 materials were used in research as PCMs.Ukrainczyk and et.al[4] reported an experimental investigation of thermal properties for five paraffin waxes in order to evaluate their potential use as a Abstract: In this experimental study a test was carried out on a paraffin wax-copper (PWC) thermal property, which consists of a phase change material with 10% copper powder.The PCW with rectangular shape (25cm× 25cm×30cm) size is supplied with heater within it, and installed inside an isolated tank case, which allows the water to flow over the PWC from inlet side to the outside.This sample is used as a thermal storage .The PWC is initially heated by electric heater reaching phase liquid at Temp (90℃) whereas the supply water temperature ranged (19-20°C).An engineering equation solver (EES) pc program has been created to register the parameters (outlet water Temp; heat transfer rate, and the time needs to release total the thermal energy).The outcomes showed that outlet water Temp gained due to thermal storage in the water tank (PWC) is more than with (PCM) which comprises of paraffin wax without copper powder.The water temperature decreases with the increase of water flow rate of mass and the freeze time for the sample takes a long time period for lower flow rate of mass.The ratio of the thermal storage for mixture paraffin wax increased by 30.7% compared with a normal wax pure.
