Calculate gas phase diffusion coefficient using Chapman-Enskog equation.

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.
P (str (dict key) or numeric) – Name of the dictionary key on phase containing the ndarray of pressure values, in units of [Pa]. If a numerical value is passed (i.e. a scalar or ndarray) it gets used directly.
