Member Function Documentation
◆ transportType()
|
inlinevirtual |
Identifies the Transport object type.
Each derived class should override this method to return a meaningful identifier.
Reimplemented from MixTransport.
Definition at line 30 of file UnityLewisTransport.h.
◆ getMixDiffCoeffs()
|
inlinevirtual |
Returns the unity Lewis number approximation based diffusion coefficients [m^2/s].
Returns the unity Lewis number approximation based diffusion coefficients for a gas, appropriate for calculating the mass averaged diffusive flux with respect to the mass averaged velocity using gradients of the mole fraction.
\[ D^\prime_{km} = \frac{\lambda}{\rho c_p} \]
In order to obtain the expected behavior from a unity Lewis number model, this formulation requires that the correction velocity be computed as
\[ V_c = \sum \frac{W_k}{\overline{W}} D^\prime_{km} \nabla X_k \]
- Parameters
