A New Thermodynamic Function for Phase-Splitting at Constant Temperature, Moles, and Volume

We introduce a new thermodynamic function for phase-split computations at constant temperature, moles, and volume. The new volume function Fi introduced in this work is a natural choice under these conditions. Phase equilib...
