As it cools from the molten state, its various phase changes can cause components to distort and crack.
In addition, temperature distributions of the thermal energy during laser surface treatment enabled the prediction of various phase changes.
The interfacial heat and mass transfer at nano-scale are the key procedure of various phase changes phenomena, and are of significant importance for both science and engineering applications.
In this work, we utilize a figure-of-merit (FOM) to compare the performance of various phase-change materials (PCMs) in managing short bursts of high-power heat flux, particularly those associated with microprocessors undergoing bursty operation on a time scale of approximately one second.
Various types of phase change material (PCM) products are available but under the current fire safety guidelines their usage may be restricted due to their flammability, as is the case for some insulation materials.
For the PEG/CNIC PCMs with various PEG content, the phase change temperatures and the extent of supercooling show little difference and are much lower than those of pure PEG.
In this study, startup characteristics of a pump-assisted capillary phase change loop under various operational conditions were experimentally investigated.
Also in the view of using heat storage materials, especially phase change materials (PCMs), various types of packing bed and selective coated absorbers give good improvement of the efficiency of SAHs.
Furthermore, the analysis of solar thermal systems, various system applications such as air, water, air/water, phase change material PCM and Nanofluid systems are summarized.
The effect of various influencing factors, especially mass flow rate of water, phase change temperature and thermal conductivity of PCM, were investigated numerically.
