liquid_pure_bb#

liquid_pure_bb(phase, T='pore.temperature', Tc='param.critical_temperature', Tb='param.boiling_temperature', Pc='param.critical_pressure')[source]#

Computes the surface tension of a pure liquid in 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.
T (str (dict key) or numeric) – Name of the dictionary key on phase containing the ndarray of temperature values, in units of [K]. If a numerical value is passed (i.e. a scalar or ndarray) it gets used directly.
Tc (str (dict key) or numeric) – Name of the dictionary key on phase containing the ndarray of critical temperature values, in units of [K]. If a numerical value is passed (i.e. a scalar or ndarray) it gets used directly.
Tb (str (dict key) or numeric) – Name of the dictionary key on phase containing the ndarray of boiling temperature values, in units of [K]. If a numerical value is passed (i.e. a scalar or ndarray) it gets used directly.
Pc (str (dict key) or numeric) – Name of the dictionary key on phase containing the ndarray of critical pressure values, in units of [Pa]. If a numerical value is passed (i.e. a scalar or ndarray) it gets used directly.

Returns:

value – A numpy ndarray containing surface tension values scaled to the temperature [N/m]

Return type:

ndarray
