Mixture

class thermosteam.mixture.Mixture(rule, Cn, H, S, H_excess, S_excess, mu, V, kappa, Hvap, sigma, epsilon, include_excess_energies=False)

Create an Mixture object for estimating mixture properties.

Parameters

• rule (str) – Description of mixing rules used.

• Cn (function(phase, mol, T)) – Molar heat capacity mixture model [J/mol/K].

• H (function(phase, mol, T)) – Enthalpy mixture model [J/mol].

• S (function(phase, mol, T, P)) – Entropy mixture model [J/mol].

• H_excess (function(phase, mol, T, P)) – Excess enthalpy mixture model [J/mol].

• S_excess (function(phase, mol, T, P)) – Excess entropy mixture model [J/mol].

• mu (function(phase, mol, T, P)) – Dynamic viscosity mixture model [Pa*s].

• V (function(phase, mol, T, P)) – Molar volume mixture model [m^3/mol].

• kappa (function(phase, mol, T, P)) – Thermal conductivity mixture model [W/m/K].

• Hvap (function(mol, T)) – Heat of vaporization mixture model [J/mol]

• sigma (function(mol, T, P)) – Surface tension mixture model [N/m].

• epsilon (function(mol, T, P)) – Relative permitivity mixture model [-]

• include_excess_energies=False (bool) – Whether to include excess energies in enthalpy and entropy calculations.

Notes

Although the mixture models are on a molar basis, this is only if the molar data is normalized before the calculation (i.e. the mol parameter is normalized before being passed to the model).
