liquid_pure_ls(phase, T='pore.temperature', MW='param.molecular_weight', Tc='param.critical_temperature', Pc='param.critical_pressure', omega='param.acentric_factor')[source]#

Computes the viscosity of a pure liquid 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.

  • MW (str (dict key) or numeric) – Name of the dictionary key on phase containing the ndarray of molecular weight values, in units of [g/mol]. 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.

  • 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.

  • omega (str (dict key) or numeric) – Name of the dictionary key on phase containing the ndarray of accentric factor values, which is dimensionless. If a numerical value is passed (i.e. a scalar or ndarray) it gets used directly.

Returns:

mu – An ndarray of Np length containing the viscosity of the mixture in each pore

Return type:

ndarray
