liquid_mixture_wsd#

liquid_mixture_wsd(phase, sigmas='pore.surface_tension.*', rhos='pore.density.*', MWs='param.molecular_weight.*')[source]#

Computes the surface tension of a liqiud mixture with its own vapor using the correlation in [1]

Parameters:

  • phase (OpenPNM Phase object) – The phase object to which this model is associated (i.e. attached). This controls the length of the calculated array(s), and also provides access to other necessary properties.

  • rhos (str) – The dictionary key containing the density in kg/m3

  • MWs (str (dict key) or dict of numeric values for each species) –

sigmas : str (dict key) or scalar

Returns:

sigma – A numpy ndarray containing surface tension values

Return type:

ndarray
