WebDownloadable (with restrictions)! Phase change materials show promise to address challenges in thermal energy storage and thermal management. Yet, their energy density and power density decrease as the transient melt front moves away from the heat source. Here, we propose an approach that achieves the spatial control of the melt-front location … WebComputational Fluid Dynamics (CFD) modeling and simulation for phase change materials (PCMs) is a technique to analyze the performance and behavior of PCMs. The CFD models have been successful in studying and analyzing the air quality, natural ventilation and stratified ventilation, air flow initiated by buoyancy forces and temperature space for the …
WebIn this work, we explore the properties of the nonequilibrium phase transition in dynamics that occurs in trajectory space between high- and low-mobility basins in a set of model polymer freestanding films. In thick films, the film-averaged mobility transition is broader than the bulk mobility transition, while in thin films it is a variant of ... WebHowever, as a dynamic interfacial phenomenon, deep understanding of its process and mechanism, including liquid re-wetting and vapor departure, is still challenging. ... Liquid Super-Spreading Boosted High-Performance Jet-Flow Boiling for Enhancement of Phase-Change Cooling Adv Mater. 2024 Apr 6;e2210557. doi: 10.1002/adma.202410557.
WebApr 1, 2024 · This method relies on adding high thermal conductivity fillers, such as nanoparticles, to enhance the phase change process. In the long term, dynamic tuning heat transfer provides a superior means of tuning control the heat transfer efficiency and speed. In this study, a nanofluid phase change material was prepared by adding … A disorder-broadened first-order transition occurs over a finite range of temperatures where the fraction of the low-temperature equilibrium phase grows from zero to one (100%) as the temperature is lowered. This continuous variation of the coexisting fractions with temperature raised interesting possibilities. On cooling, some liquids vitrify into a glass rather than transform to the equilibrium crystal phase. This happens if the cooling rate is faster than a critical cooling rat…
