In energy balance calculations, sensible heat change is determined using a property of matter called the heat capacity at constant pressure, or just heat capacity. We will use the symbol Cp for heat capacity; units for Cp are, for example, J gmol−1 K−1, cal g−1°C−1, and ...
Latent heat thermal energy storagePhase change materialRectangular storageLatent heat thermal storage (LHTS) using phase change materials (PCMs) is one of the efficient and useful technologies in conservation and retention of thermal energy. One of the main advantages of this technology is the ...
For the first obstacle, existing multi-temperature control techniques minimize temperature interactions by enhancing the thermal insulation in between4,31. This suggests that when the temperature differences among the storage spaces are significant, more energy may be employed to negate the negative ...
A shift of El Niño onset location from eastern Pacific (EP) to western Pacific (WP) occurred around 1970. It was accompanied by a faster mean sea surface temperature (SST) warming in WP and a change of precursory SST and wind anomaly patterns. The eig
Phase change material (PCM) laden with nanoparticles has been testified as a notable contender to increase the effectiveness of latent heat thermal energy storage (TES) units during charging and discharging modes. In this study, a numeri... M Amidu,M Ali,A Alkaabi,... - 《Scientific Reports...
Solid−liquid phase transformation has the advantages of small volume variation, large latent heat of phase transformation and excellent thermal stability during phase transformation. In addition, solid−liquid phase transformation does not require additional energy during application (Wang et al., 2015...
In the case of direct solid-vapor transitions, the energy required is given by the equation Q = mLs, where Ls is the heat of sublimation, which is the energy required to change 1.00 kg of a substance from the solid phase to the vapor phase. Ls is analogous to Lf and Lv, and its ...
In adiabatic thermodynamic process, the heat does not flow to or out of the system, the work done by the system comes at the expense of its internal energy. In quasi-static adiabatic process, the entropy of the system ...
The Southern Ocean is a primary heat sink that buffers atmospheric warming and has warmed substantially, accounting for an outsized portion of global warming-induced excess heat in the climate system. However, its projected warming is highly uncertain an
Seasonal ice in lakes plays an important role for local communities and lake ecosystems. Here we use Large Ensemble simulations conducted with the Community Earth System Model version 2, which includes a lake simulator, to quantify the response of lake i
