Residual enthalpy
In thermodynamics, a departure function is defined for any thermodynamic property as the difference between the property as computed for an ideal gas and the property of the species as it exists in the real world, for a specified temperature T and pressure P. Common departure functions include those for enthalpy, entropy, and internal energy. Departure functions are used to calculate real fluid extensive properties (i.e. properties which ar… WebThe enthalpy change of any phase transition is trivially coupled to the free-energy change of the phase transition. We propose a consistent scheme for calculating the free-energy change, as well as the associated enthalpy change, using residual thermodynamics for every component in all phases, this includes the hydrate phase.
