This class is used to compute transport properties for a phase of matter.
Not all transport properties are implemented in all transport models.
Binary diffusion coefficients [m^2/s].
Electrical conductivity. [S/m].
Mixtureaveraged diffusion coefficients [m^2/s] relating the massaveraged diffusive fluxes (with respect to the mass averaged velocity) to gradients in the species mole fractions.
Mixtureaveraged diffusion coefficients [m^2/s] relating the diffusive mass fluxes to gradients in the species mass fractions.
Mixtureaveraged diffusion coefficients [m^2/s] relating the molar diffusive fluxes to gradients in the species mole fractions.
Multicomponent diffusion coefficients [m^2/s].
Thermal conductivity. [W/m/K].
Return a onedimensional array of the species thermal diffusion coefficients [kg/m/s].
Get/Set the transport model associated with this transport model.
Setting a new transport model deletes the underlying C++ Transport object and replaces it with a new one implementing the specified model.
Viscosity [Pas].
Bases: cantera._cantera.Transport
DustyGasTransport(*args, **kwargs)
Implements the “dusty gas” model for transport in porous media.
As implemented here, only species transport (multi_diff_coeffs) is handled. The viscosity, thermal conductivity, and thermal diffusion coefficients are not implemented.
Mean particle diameter of the porous medium [m].
Mean pore radius of the porous medium [m].
Get the molar fluxes [kmol/m^2/s], given the thermodynamic state at two nearby points.
Parameters: 


Permeability of the porous medium [m^2].
Porosity of the porous medium [dimensionless].
Tortuosity of the porous medium [dimensionless].
Bases: object
Transport data for a single gasphase species which can be used in mixtureaveraged or multicomponent transport models.
The arguments passed to the constructor are equivalent to the properties of the object, with values in MKS units. To set properties in nonMKS units, use the set_customary_units method.
Get/Set Pitzer’s acentric factor. [dimensionless]
Get/Set the LennardJones collision diameter [m]
Get/Set the permanent dipole moment of the molecule [Coulombm].
Get/Set the string specifying the molecular geometry. One of atom, linear, or nonlinear.
Get/Set the polarizability of the molecule [m^3].
Get/Set the rotational relaxation number (the number of collisions it takes to equilibrate the rotational degrees of freedom with the temperature).
Set the parameters using “customary” units: diameter in Angstroms, well depth in Kelvin, dipole in Debye, and polarizability in Angstroms^3. These are the units used in in CKstyle input files.
Get/Set the LennardJones well depth [J]
