feos.saftvrqmie.SaftVRQMieRecord¶

class feos.saftvrqmie.SaftVRQMieRecord(m, sigma, epsilon_k, lr, la, fh, viscosity=None, diffusion=None, thermal_conductivity=None)¶

Pure-substance parameters for the Saft-VRQ Mie equation of state.

Parameters:

m (float) – Segment number
sigma (float) – Structure parameter of the Mie potential in units of Angstrom.
epsilon_k (float) – Energetic parameter of the Mie potential in units of Kelvin.
lr (float) – Repulsive exponent of the Mie potential.
la (float) – Attractive exponent of the Mie potential.
fh (int) – Feynman-Hibbs order. One of {0, 1, 2}. fh = 0 disables quantum corrections so that effectively, the SAFT-VR Mie equation of state is used.
viscosity (List[float], optional) – Entropy-scaling parameters for viscosity. Defaults to None.
diffusion (List[float], optional) – Entropy-scaling parameters for diffusion. Defaults to None.
thermal_conductivity (List[float], optional) – Entropy-scaling parameters for thermal_conductivity. Defaults to None.
