ERROR: Latent heat cannot be less than zero! could you please help me to understand and resolve this error sure, in ansys it is suggested to consider latent heat for refrigerant in liquid material as zero in ansys fluent, latent heat is calculated from standard state enthalpy of phase partici...
先说一个，如果两个数据没有给合适，初始化的时候会报错，报错内容为“ERROR: Latent heat cannot be less than zero!”那么标准状态焓和汽化潜热是什么关系呢？查询手册，可以得到的汽化潜热的公式为：这里L表示汽化潜热，HV(Tsat)为气体在饱和状态下的焓值，Hl(Tsat)为液体在饱和状态的焓值。而焓值计算的公式...
The latent heat of vaporization of water at atmospheric pressure is 2256.7 kJ/kg. If instead of boiling the water, we are condensing it, we would need to extract (in a condenser) 2256.7 kJ/kg. The values vary with pressure. The significance of this theory cannot be underestimated, since ...
For a given volume the latent heat storage is significantly higher than that of sensible heat storage. Latent heat provides substantially high energy storage density and maintains small temperature difference between the storage and release of heat [6]. LHSMs can be of the form Solid–Solid (S–...

by Harikrishnan et al.44 and Sharma et al.54 have shown that such model does not match experimental meas- urements, and that a similar equation to the one employed for calculating the thermal properties of nanofluids cannot be straightforwardly used to predict the latent heat of NePCMs...
counts cannot be less than 0, suggesting an initial count of 1 for each shape. However, an initial count of 1 would yield a division by 0, so for numerical stability some value above 1 is needed. Since shapes are either seen or not seen, conceptual considerations suggest an integer value...
Latent and sensible heat fluxes are the primary mechanism by which the ocean transfers much of the absorbed solar radiation back to the atmosphere. The two fluxes cannot be directly observed by space sensors, but can be estimated from wind speed and sea–air humidity/temperature differences using...
In such circumstances, meeting CO2 emission reduction targets remain a challenge for the country if alternative energy resources or technologies cannot be applied for heating. The heating demand can be met by green technologies and advanced systems such as a solar thermal, air-water heat pump, ...
In other words, depending on what is being stored, different melting temperatures cannot be provided for different food products or other biological materials. An example of such a prior device is the modular cold-storage pallet, including an insertable heat sink material utilizing latent heat, ...
