“…The results obtained in these experiments can be compared to the ones obtained previously in short term experiments [8] where the tests were performed for 3, 7 and 14 days, in experiments without graphite and in open tubes. These results are contained in the figures we show below, too.…”

“…In an earlier paper [8], we selected different common metals and tested their corrosion resistance in contact with salt hydrates that are used as PCMs. The tests presented and evaluated were short term, since the contact time of the metal with the salt was only up to two weeks.…”

“…Following thermal cycling tests, Porisini concluded that stainless steel was the most corrosion resistant of these metals for use with salt hydrates, though copper was shown to have a corrosion zone that did not increase after long periods of time. Cabeza et al [3][4][5][6] examined the corrosion resistance of five metals, including aluminium and copper, which were in contact with molten salt hydrates with melting temperatures of the order 0-10, 32-36 and 48-58 • C. Table 1 summarises the corrosion rates for copper and aluminium found in each case. As shown in Table 1, aluminium is prone to localised pitting corrosion when in contact with chlorides resulting in the formation of Al(OH) 3 .…”

“…The geometric parameters of the PCM container must correspond to the melting time and daily insolation process from a solar collector at specific location in order to ensure long term thermal performance of PCM storage systems. Cabeza et al [11][12][13][14][15] highlighted a technique to encapsulate the PCM to avoid the liquid phase flow away from the specific location applied. The two principles of PCM encapsulation include microencapsulation and macro-encapsulation.…”

Abstract. As the development of solar energy is getting advance from time to time, the concentration solar technology also get the similar attention from the researchers all around the globe. This technology concentrate a large amount of energy into main spot. To collect all the available energy harvest from the solar panel, a thermal energy storage is required to convert the heat energy to one of the purpose such as electrical energy. With the idea of energy storage application that can be narrow down to commercial application such as cooking stove. Using latent heat type energy storage seem to be appropriate with the usage of phase change material (PCM) that can release and absorb heat energy at nearly constant temperature by changing its state. Sodium nitrate (NaNO 3 ) and potassium nitrate (KNO 3 ) was selected to use as PCM in this project. This paper focus on the heat loading process and the melting process of the PCM in the energy storage using a computer simulation. The model of the energy storage was created as solid three dimensional modelling using computer aided software and the geometry size of it depend on how much it can apply to boil 1 kg of water in cooking application. The materials used in the tank, heat exchanger and the heat transfer fluid are stainless steel, copper and XCELTHERM MK1, respectively. The analysis was performed using a commercial simulation software in a transient state. The simulation run on different value of velocity but kept controlled under laminar state only, then the relationship of velocity and heat distribution was studied and the melting process of the PCM also has been analyzed. On the effect of heat transfer fluid velocity, the higher the velocity resulted in higher the rate of heat transfer. The comparison between the melting percentages of the PCMs under test conditions show that NaNO 3 melts quite faster than KNO 3 .
