Regarding the energy of each molecule, in gases this is even greater than in liquids, so there is also a release of energy when going from the first phase to the second.
WebThe dimensioning of the recovery line is based on isentropic outflow and the amount of vaporized LH2 during the whole refueling process. By considering the energy balances of the material, heat transfer and the (latent) heat of vaporization of LH2, an evaporated fraction of the mass flow can be calculated: (43) m ˙ vap = q (T) · A Δ h v
