Fixed properties

Information

Assumptions:

  1. The generalized resistivities (η, θ) are fixed (e.g., independent of thermodynamic state).
  2. Ideal gas

The default resistivities (η = 1/(207.2e-7*U.Pa*U.s) and θ = U.m*U.K/(26.8e-3*U.W)) are based on data of gas at 1 atm and 300 K from Incropera and DeWitt [Incropera2002, pp. 920–921]. Table 1 lists the properties at other temperatures.

The specific heat capacity is not fixed because it would affect the chemical potential and result in an incorrect cell potential.
