摘要：

In this study a mathematical model is used to predict the performance of the solar still using the phase change material to enhance the thermal performance of the solar still. Experimental is conducted with and without using PCM like lauric acid and calcium chloride hexahydrate, and the result shows that thermal efficiency increase using PCM of about 21%, 20% in calcium chloride hexa hydrate and lauric acid than without using PCM in the solar still. A mathematical model is develop, which is used to find the temperature of glass cover, water and the basin for predicting the theoretical value in order to match with the experimental result. The comparison result shows the 95% of good agreement between the theoretical value and experimental results for glass, water and basin temperature. Enhancing the heat transfer is the major role in order to increase the productivity of water from solar desalination still.
