get_mix_vals#

Mixture.get_mix_vals(propname, mode='linear', power=1)[source]#

Get the mole fraction weighted value of a given property for the mixture

Parameters:

• propname (str) – The property to fetch, such as 'pore.viscosity'.

• mode (str) –

  The type of weighting to use. Options are:

  mode
  ’linear’	(default) Basic mole fraction weighting of the form: $z=\mathrm{\Sigma }(x_i\cdot {\text{z}}_i)$
  ’logarithmic’	Uses the natural logarithm of the property as: $ln(z)=\mathrm{\Sigma }(x_i\cdot ln({\text{z}}_i))$
  ’power	Applies an exponent to the property as: ${\text{z}}^{power}=\mathrm{\Sigma }(x_i\cdot {\text{z}}_i^{power})$

• power (scalar) – If mode='power' this indicates the value of the exponent, otherwise this is ignored.

Returns:

vals – An ndarray with the requested values obtained using the specified weigthing.

Return type:

ndarray
