Table 3 Segmentation of frozen PCM values and the percentage impact of fins on its solidification in a radial-finned tank with a first-type boundary condition.
Number of radial fins | Time (s) | The effective area under the freezing front curve influenced by the fin | The effective volume of frozen PCM influenced by the fin in each cell | The volume of frozen PCM influenced by the first region in each cell | The total volume of frozen PCM in each cell | The total volume of each cell | The percentage impact of fins on the increase in frozen PCM volume |
