Tóm tắt

This study carries out a series of complex unsteady three-dimensional (3D) computational analyses that were validated by experimental tests to examine the performance enhancement of a cylindrical shell-and-coil ice storage enclosure by employing various spiral longitudinal fin geometries covering the heat transfer fluid (HTF) tubes throughout the transient process of solid-liquid phase change. The phase change material (PCM) in this work was selected to be water and the tubes and fins were chosen to be made of copper alloy. To study how this type of fin accelerates the charging process, several dimensionless parameters related to the spiral longitudinal fin geometries were defined, which included dimensionless fin length (
