With a view to finding an improved thermal storage capability of solar water tank, the thermodynamics of a thermal storage tank with a eutectic phase change material was studied. The thermal exchange between the heat transfer fluid (HTF) and the PCM were investigated. The PCM are helpful in solar-systems for helping to satisfy the energy-demand when alternative energy isn't obtainable. The solar-water heaters based on phase change materials (PCMs) have the advantage of high storagedensity at a low temperature range. However, there are some simplifying assumptions that were established during this paper. Underneath simplifying assumptions, it's shown that the governing equations are the three energy conservation equations written for the thermal transfer fluid, the tank and the PCM. The PCM energy conservation is written in-terms of physical-property (enthalpy). All of the differential equations are numerically resolved in line with a finite distinction scheme technique. Simulations are performed to derive the temperature profiles in the PCM storage tank region at the solar water heater. Several simulation runs are created for ambient-conditions by varying the water temperature of the heat transfer fluid and finally, the simulated and the experimental results was additionally created for optimum comparison.
