EosType.Aassoc(rho, T, xi)[source]

Return a vector of association site contribution of Helmholtz energy.

\(\frac{A^{association}}{N k_{B} T}\)

Parameters:

  • rho (numpy.ndarray) – Number density of system [\(mol/m^3\)]

  • T (float) – Temperature of the system [K]

  • xi (numpy.ndarray) – Mole fraction of each component, sum(xi) should equal 1.0

Returns:

Aassoc – Helmholtz energy of ideal gas for each density given.

Return type:

numpy.ndarray
