EosType.helmholtz_energy(rho, T, xi)[source]

Return a vector of Helmholtz energy.

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

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:

A – Total Helmholtz energy for each density value given.

Return type:

numpy.ndarray
