Implementation of the UNIQUAC model in the OpenCalphad software

open access: yesFluid Phase Equilibria, 2020
The UNIQUAC model is often used, for example in engineering, to obtain activity coefficients in multicomponentsystems, while the CALPHAD method is known for its capability in phase stability assessmentand equilibrium calculations. In this work, we combine them by representing the UNIQUAC model accordingto the CALPHAD method and implementing it in the ...
