Abstract

This paper presents the computational investigation of the charging characteristics of PCM inside a latent heat thermal energy storage (LHTES) unit that consists of a horizontal heat exchanger type of the inner tube and outer shell using ANSYS/FLUENT software. The melting process numerically tested for the heat transfer fluid HTF (water) inlet temperature (60, 70, and 80 °C), and the PCM's initial temperature is 15 °C. Also, this study examined the effect of the mushy zone constant. Extensive measures show that charging time decreases with increased water inlet temperature. The melting of PCM completes in a time of 260 minutes when using a water inlet temperature of 60 °C, while the melting time reaches 182 minutes when the water inlet temperature is 70 °C, and the melting completes in a time of 145 minutes by using the hot water entry temperature of 80 °C. When the water inlet temperature increased from 60 °C to 70 °C and 80 °C, respectively, the melting time was saved by about 30% and 44%. The best melting time reduction is achieved at an HTF inlet temperature of 80 °C. In addition, the melting time increased as constant values rose in the mushy zone. The melting times are 182, 191, and 200 minutes for mushy zone constants 105, 106, and 107, respectively. So, the mushy zone constant of 105 leads to the best reduction in melting time.
