despasito.equations_of_state.saft.gamma_sw.SaftType.Achain

SaftType.Achain(rho, T, xi)[source]

Outputs chain contribution to the Helmholtz energy \(A^{chain}/Nk_{b}T\).

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:

Achain – Helmholtz energy of monomers for each density given.

Return type:

numpy.ndarray
