# Mathematical Model of Solidification of Hydrated Salts with a Longitudinal Fin of Rectangular Profile

## Abstract

Salt hydrates are inorganic phase change materials (PCMs) that can absorb and release heat energy during the phase change process. There are good properties for many applications, such as high latent heat, non-flammable, good energy storage capacity and expensive. Salt Hydrates are used for storage applications such as greenhouses and PCMs energy storage. In this paper, a mathematical model of solidification of a PCMs called hydrated salt is developed and analyzed. The conditions are that the wall temperature is  25 °C, fin length is 0.05 m., fin width is 0.01 m. PCMs storage heights are 7 sizes, 0.01 – 0.07 m. in increments of 1 cm. For a height of 0.01 m, the total time of solidification of PCMs is minimum. For at a height of 0.05 – 0.07 meters, it takes the same time for solidification and takes the most time. From the mathematical model it is found that the time, wall temperature, and fin size affect the distance of PCMs solidification.
