Summary: This research investigates the melting process of phase change material (PCM) in a thermal energy storage chamber with various changes in fins, such as discrete strip fins and metal foam gradient. The study explores the effects of geometric parameters, fin arrangement, and fin material on the melting process. Results show that the number of fins affects the melting time, and discrete fins reduce the melting time by about 50%. The temporal changes in wall temperature also impact the melting process, and the spatial distribution of wall temperature has a significant influence on melting time.

Summary: To accurately simulate the heat storage performance of metal foam composite phase change materials (PCMs), this study proposed modifying the structure of the original body-centered cubic (BCC) unit to approach the open-cell structure of the real foam. By analyzing the structural parameter (gamma) and effective thermal conductivity (ETC), it was found that improving gamma is helpful in representing the actual metal foam structure when the porosity of the BCC unit is lower than 0.9395. Furthermore, for porosity values above 0.9395, the experimental ETC can be gradually approached by improving gamma.

Summary: This paper introduces a novel multi-task learning data-driven model called GBLS Booster for accurately assessing the state of health (SOH) and remaining useful life (RUL) of lithium batteries. The model combines the strengths of GBLS and the CNN-Transformers algorithm-based Booster, and the Tree-structured Parzen Estimator (TPE) algorithm is used for optimization. The study devises 10 healthy indicators (HIs) derived from readily available sensor data to capture variations in battery SOH. The random forest method (RF) is employed for feature refinement and data dimension reduction, while the complete empirical mode decomposition (CEEMDAN) method and the Pearson correlation coefficient are used for noise reduction and data point elimination in RUL prediction. The proposed model demonstrates exceptional accuracy, robustness, and generalization capabilities.
