Heat transfer through the membrane by conduction and by movement of vapor across the membrane (latent heat of vaporization). The influence of mass transfer on the heat transfer can be ignored [75,97,107–109,114] (3.29)Qm=kmδTf,m−Tp,m+J△Hv (3.30)Qm=hmTf,m−Tp,m+J△Hv where...
The meaning of LATENT HEAT is heat given off or absorbed in a process (such as fusion or vaporization) other than a change of temperature.

This phase change driven by latent heat of vaporization offers a heat pipe the capability of transferring high heat loads at small temperature gradients. The vapour pressure build-up at the evaporator section drives the working fluid from the evaporator end to the condenser end, where it releases...
The term ɛ denotes the volume fraction of a single phase, v denotes air velocity, δT/δt = change of temperature with respect to time, Cp/cp = specific heat, Keff is the effective thermal conductivity,Δhvap is the heat of vaporization of the liquid phase, and Ql is the heat of...
vaporization of the third working fluid; and enabling the third working fluid egressing from the third heat exchanger to be cooled via one or more of a fourth heat exchanger, a reservoir, and the atmosphere before circulating the third working fluid back to the third heat exchanger; wherein ...
