The paper analyzes the behavior of a Latent Heat Thermal Energy Storage system (LHTES) with a Phase Change Material (PCM), with and without aluminum foam. A numerical investigation in a two-dimensional domain is accomplished to investigate on the system thermal evolution. The enthalpy-porosity ...
On the boundary conditions selected, cooling alone is too slow to effect convection. Convective motions arise only by the additional release of latent heat of crystallization owing to the growth of the inner core. A fundamental feature of the model is the choice of a subadiabatic initial ...
Based on the ε_c-BF, a steady state distributed parameters model is put forward in the numerical simulation of refrigerant circuitry in evaporators in this paper. Applying this model, the heat transfers and flow characteristics of two-rows counter-flow evaporators which used the refrigerant repl...

It was found that using a double-side heater (DSH) and a composite argon gas duct system could speed up the release of latent heat and enhance the pulling speed [12]. By independently controlling the side heaters, a low heater power on the lower side heater (LSH) can decrease the ...
It can be found that there are many relative simulation studies on sudden expansion of pipes, focusing on the pressure loss characteristics during the flow. Furthermore, due to the fact that the boiling point and gasification latent heat of the gas extinguishing agent are significantly different ...
Experimental validation was performed in this study to verify the efficacy of numerical models for predicting the location of solid-liquid interface in an axi-symmetric configuration during both melting and solidification in a Latent Heat Storage Unit (LHSU). Development of analytical solutions for pre...
The role of dew in the water and heat balance of bare loess soil in the Negev Desert: quantifying the actual dew deposition on the soil surface During nighttime, latent heat fluxes to or from the soil surface are usually very small and the absolute amounts of dew deposition are accordingly...
