Efficient and Precise Representation of Pure Fluid Phase Equilibria with Chebyshev Expansions

Abstract
In this work, it is shown that Chebyshev expansions can be used to provide a representation of pure fluid phase equilibria models that is approximately 400 times faster to evaluate than the full phase equilibrium calculation with multiparameter equations of state. The use of extended precision for the phase equilibrium calculation allows for the construction of a numerical representation approaching the numerical precision of double-precision arithmetic.Citation
