| Popis: | The continuous increase in the level of green-house gas emissions and the depletion of fossil fuels are identified, as the major driving forces behind efforts to effectively utilize different sources of renewable energy. Solar energy considered one of the most prospective sources of this energy. This review paper mainly focuses on the majority of heat-transfer enhancement techniques between the phase-change material (PCM) and the heat-transfer fluid (HTF) based on the application of fins embedded in the PCM. This study also investigated the geometrical dimensions, dimensionless numbers, and fin location through numerical and experimental works conducted to assess the influences of these parameters on the thermal performance of PCM-latent heat thermal energy storage (LHTES) containers. The best enhancement is achieved using the longitudinal finned configurations because of its easy design and fabrication, especially along circumference of the cylindrical PCM containers. The circular-finned tube was also more effective than the pinned-tube for different shell and tube. PCMs based on heat sinks with internal pin fins were widely used for the thermal management of various pieces of electronic products. The heat enhancement factor was effectively dependent on increasing the numbers and dimensions of these fins. Further researches still require to explore the possible geometrical designs of fins and their key findings, which have more effect on the thermal performance of the finned-LHTES system. |
