C++ implementation of enthalpy-entropy flash calculations with superancillary equations

Published by National Institute of Standards and Technology | National Institute of Standards and Technology | Metadata Last Checked: August 02, 2025 | Last Modified: 2022-01-19 00:00:00
This repository implements the code to accompany the paper "Accelerating Enthalpy-Entropy Iterative Calculations With Superancillary Phase Boundaries" in the Energy journal by Ian Bell.The code uses superancillary equations (Chebyshev expansions) to speed up the phase-boundary determination and two-phase iterative calculations by a factor of approximately 500 without a loss in precision.
