doublereal viscosity ( )

virtual

Viscosity of the mixture (kg /m /s)

The viscosity is computed using the Wilke mixture rule (kg /m /s)

\[ \mu = \sum_k \frac{\mu_k X_k}{\sum_j \Phi_{k,j} X_j}. \]

Here \( \mu_k \) is the viscosity of pure species k, and

\[ \Phi_{k,j} = \frac{\left[1 + \sqrt{\left(\frac{\mu_k}{\mu_j}\sqrt{\frac{M_j}{M_k}}\right)}\right]^2} {\sqrt{8}\sqrt{1 + M_k/M_j}} \]

Returns: Returns the viscosity of the mixture ( units = Pa s = kg /m /s)

void getMixDiffCoeffs ( doublereal *const d )

virtual

Returns the Mixture-averaged diffusion coefficients [m^2/s].

Returns the mixture averaged 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. Note, for the single species case or the pure fluid case the routine returns the self-diffusion coefficient. This is needed to avoid a Nan result in the formula below.

This is Eqn. 12.180 from "Chemically Reacting Flow"

\[ D_{km}' = \frac{\left( \bar{M} - X_k M_k \right)}{ \bar{\qquad M \qquad } } {\left( \sum_{j \ne k} \frac{X_j}{D_{kj}} \right) }^{-1} \]

Parameters

[out] d Vector of mixture diffusion coefficients, \( D_{km}' \) , for each species (m^2/s). length m_nsp

void getMixDiffCoeffsMole ( doublereal *const d )

virtual

Returns the mixture-averaged diffusion coefficients [m^2/s].

These are the coefficients for calculating the molar diffusive fluxes from the species mole fraction gradients, computed according to Eq. 12.176 in "Chemically Reacting Flow":

\[ D_{km}^* = \frac{1-X_k}{\sum_{j \ne k}^K X_j/\mathcal{D}_{kj}} \]

Parameters

[out] d vector of mixture-averaged diffusion coefficients for each species, length m_nsp.

Reimplemented from Transport.

void getMixDiffCoeffsMass ( doublereal *const d )

virtual

Returns the mixture-averaged diffusion coefficients [m^2/s].

These are the coefficients for calculating the diffusive mass fluxes from the species mass fraction gradients, computed according to Eq. 12.178 in "Chemically Reacting Flow":

\[ \frac{1}{D_{km}} = \sum_{j \ne k}^K \frac{X_j}{\mathcal{D}_{kj}} + \frac{X_k}{1-Y_k} \sum_{j \ne k}^K \frac{Y_j}{\mathcal{D}_{kj}} \]

Parameters

[out] d vector of mixture-averaged diffusion coefficients for each species, length m_nsp.
