“…According to the effective graphite density and graphite orientation, it is found that the thermal conductivity of these composites is as high as 70W/(m • K) (2). On analytical and numerical study aspect, The melting process of porous materials is simulated by local thermal equilibrium hypothesis and local thermal non-equilibrium hypothesis (3). Extended surface and encapsulation of the PCM are two kinds of other approaches to reduce the PCM thermal resistance (4), as well as using heat pipes (5).…”

Latent heat thermal energy storage (LHTES) is a promising technology in prefabricated cabin energy system. This paper proposed a new thermal energy storage (TES) system with phase-change material (PCM) embedded in metal foam and heating source is steam or hot water. The mathematical formulas and numerical models of representative units are studied. The effect of natural convection is considered in the simulation of melting process. Finite volume method is used to discretize the governing equation The Forchheimer-Darcy law is used to model the porous resistance and a local thermal equilibrium model is developed. The model is firstly validated against low temperature experiments from the literature and then used to simulate the charging behaviour of LHTES system proposed by this paper. Foamed metal and fin are effective means to improve the heat transfer performance and shorten the melting time of heat storage system. In this paper, the effects of pore density, porosity, wall temperature and fin spacing on temperature change and melting rate are discussed.

With the improvement of living standards, there is a growing demand for clothing that offers both comfort and functionality. Nanomaterials have emerged as a hot topic in clothing design due to their unique structure and performance characteristics. In this study, we develop a composite nanofabric with exceptional water resistance and breathability using polyurethane (PU), fluorinated polyurethane (FPU), and polyvinyl butyral (PVB), namely PU-FPU-PVB composite nanofabric. The mechanical properties, wettability, waterproofing, and thermal comfort are evaluated. The results demonstrate that optimizing the TPU and PVB contents is crucial for obtaining PU-FPU-PVB composite nanofabrics with exceptional performance. Low TPU concentrations fail to provide sufficient viscosity for even dispersion within the hot melt adhesive mesh film, while higher concentrations enable better dispersion due to increased viscosity provided by TPU. Additionally, increasing the content of PVB from 0 wt% to 100 wt% led to decreased moisture permeability from 10.5 kg ·m−2 · d−1 to 3.0 kg ·m−2 · d−1 during thermal comfort testing. Its permeability dropped from 22.5 mm/s to 2.8 mm/s under these conditions. These findings indicate that our designed composite nanofabric exhibits excellent thermal comfort when incorporating appropriate levels of PVB into its composition, making it an ideal high-performance material for waterproof and breathable fabrics with superior comfort and functionality in clothing design applications. In conclusion, PU-FPU-PVB composite nanofabrics hold great potential for fostering the innovative advancement of nanomaterials in the realm of clothing design.
