get_mix_vals#

StandardLiquidMixture.get_mix_vals(propname, mode='linear', power=1)#

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: \(z = \Sigma (x_i \cdot \z_i)\)

    ’logarithmic’

    Uses the natural logarithm of the property as: \(ln(z) = \Sigma (x_i \cdot ln(\z_i))\)

    ’power

    Applies an exponent to the property as: \(\z^{power} = \Sigma (x_i \cdot \z_i^{power})\)

  • 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
