reynolds(target, u0, b, temperature='pore.temperature')[source]#

Uses exponential model by Reynolds [1] for the temperature dependance of shear viscosity

Parameters
  • target (GenericPhase) – The object for which these values are being calculated. This controls the length of the calculated array, and also provides access to other necessary thermofluid properties.

  • u0 (float, array_like) – Coefficients of the viscosity exponential model (mu = u0*Exp(-b*T) where T is the temperature in Kelvin

  • b (float, array_like) – Coefficients of the viscosity exponential model (mu = u0*Exp(-b*T) where T is the temperature in Kelvin

  • temperature (str) – The dictionary key containing the temperature values (K). Can be either a pore or throat array.

Returns

  • value (ndarray) – Array containing viscosity values based on Reynolds model.
