AbstractCubicAlphaFunction Class Reference

Detailed Description

An abstract alpha function for the EOS, defining the interface for the alpha function.

This C++ code is the implementation of the analyses presented in the paper I.Bell and A. Jäger, "Helmholtz energy translations for common cubic equations of state for use in one-fluid and multi-fluid mixture models", J. Res. NIST, 2016

This code is in the public domain, though if used in academic work, we would appreciate a reference back to the paper given above.
