CoolProp::GERG2008DepartureFunction Class Reference

Detailed Description

The departure function used by the GERG-2008 formulation.

This departure function has a form like

\[ \alphar^r_{ij} = \sum_k n_{ij,k}\delta^{d_{ij,k}}\tau^{t_{ij,k}} + \sum_k n_{ij,k}\delta^{d_{ij,k}}\tau^{t_{ij,k}}\exp[-\eta_{ij,k}(\delta-\varepsilon_{ij,k})^2-\beta_{ij,k}(\delta-\gamma_{ij,k})] \]

It is symmetric so \(\alphar^r_{ij} = \alphar^r_{ji}\)
