Transport properties for solids.
|
|
|
|
This class implements a simple model for the diffusion coefficients and
|
|
the thermal conductivity of a solid. The diffusion coefficients have
|
|
modified Arrhenius form, and the thermal conductivity is constant.
|
|
All parameters are user-specified, not computed from a physical model.
|
|
|
|
Examples:
|
|
|
|
>>> tr = SolidTransport(solid_phase)
|
|
>>> tr.setThermalConductivity(0.5) # W/m/K
|
|
>>> tr.setDiffCoeff(species = "OxygenIon", A = 2.0, n = 0.0, E = 700.0)
|
|
|
|
Note that the diffusion coefficient is computed from D = A * T^n *
|
|
exp(-E/t) in m^2/s. Diffusion coefficients for unspecified species are
|
|
set to zero.
