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...
Hi,I am having an issue in ANSYS simulation. I am trying to do condensation of water vapor to water liquid but when I initialize the solution, it says latent heat cannot be less than zero. I tried to search online & it comes to my knowledge that it is re
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...
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...
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 ...

It can be concluded that low s : z d ratios (less than 0.1) are preferable to reduce loss in covariance of LE . If the use of higher s : z d ratios cannot be avoided, the Villalobos method may reduce the expected loss in covariance but only under limited conditions. In these ...
We would expect the differential of humidity to be important – if the air above is saturated then latent heat transfer will be zero, because there is no way to move anymorewater vapor into the air above. At the other extreme, if the air above is completely dry then we have maximized th...
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, ...
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...
