Once the PCM reached its freezing temperature, the pure PCM started to crystallize, and the phase change from liquid to solid initiated at a temperature of approximately 9.5 °C. Figure 5 (a) Freezing curve of dimethyl adipate and (b) melting curve of dimethyl adipate. Full size image The ...
Several studies have shown that using phase change materials (PCMs) as promising LHTES materials allows absorbing or releasing latent heat during a phase change from solid-state to liquid-state (melting process) or liquid-state to solid-state (freezing process). This system found several potential...
When the environmental temperature reaches the PCM melting point, the physical state of PCM in the fabric will change from solid to liquid, resulting in the absorption of heat; heat is released when the temperature reaches the freezing point of the PCM. Textile fabrics or garments with phase ...
(ΔS‡).iSchematic illustration of the anomalous reaction entropy change due to the difference in the transition temperature of the solid-to-liquid phase transition of the cluster at the reactant and product state. The curves in red, green and orange indicate the reaction entropy change (Δ...
Thermal Energy Storage Heat Exchanger Design: Overcoming Low Thermal Conductivity Limitations of Phase-Change Materials Recently, there has been a renewed interest in solid-to-liquid phase-change materials (PCMs) for thermal energy storage (TES) solutions in response to ambi...

Two temperature levels, one above (Thigh) and one below (Tlow) the melting temperature (Tm), are applied alternately for a defined number of cycles. Certain periods of time are necessary to obtain a complete phase change from solid to liquid and vice versa. In between these two temperature...
We know that melting is the change from solid to liquid phase while evaporation is the change from liquid to gas phase. In our system, at very low T, molecules form a layered solid occupying the 𝑥𝑦xy planes due to the in-plane attraction between molecules of the same orientation. ...
