Kamal Ariffin, supervisor Mechanical engineering Also available in printed version The freezing and melting characteristics of multiple ice balls for thermal energy storage (TES) system are analyzed and important factors such as the flow of heat transfer fluid across the multiple spherical encapsulated ice balls are identified through differentiating the gap sizes between the spheres which are 0mm, 1mm, 3mm and 5mm. Similar diameter of ice balls are used for each model. Ice is formed inside the ball which containing a phase change material when heat transfer fluid is at subzero temperature flows across it during the charging process while ice is melted when heat transfer fluid with higher temperature flows across it during the discharging process. The model geometry is simplified by assembling a cylindrical tank, plate diffusers and spherical ball in one model. The simulation is validated by comparing it with past experimental results. The results show that the charging time is significantly increased as the gap size between the spherical balls increased. Multiple spherical balls with 5 mm gaps charged 3.64 percent faster compared to the one without a gap. For the discharging process, multiple spherical balls without gap discharged slower compared to a model with a 5mm gap snhas UTM 87 p.
