Detailed Description

Class DustyGasTransport implements the Dusty Gas model for transport in porous media.

As implemented here, only species transport is handled. The viscosity, thermal conductivity, and thermal diffusion coefficients are not implemented.

The dusty gas model includes the effects of Darcy's law. There is a net flux of species due to a pressure gradient that is part of Darcy's law.

The dusty gas model expresses the value of the molar flux of species \( k \), \( J_k \) by the following formula.

\[ \sum_{j \ne k}{\frac{X_j J_k - X_k J_j}{D^e_{kj}}} + \frac{J_k}{\mathcal{D}^{e}_{k,knud}} = - \nabla C_k - \frac{C_k}{\mathcal{D}^{e}_{k,knud}} \frac{\kappa}{\mu} \nabla p \]

\( j \) is a sum over all species in the gas.

The effective Knudsen diffusion coefficients are given by the following form

\[ \mathcal{D}^e_{k,knud} = \frac{2}{3} \frac{r_{pore} \phi}{\tau} \left( \frac{8 R T}{\pi W_k} \right)^{1/2} \]

The effective knudsen diffusion coefficients take into account the effects of collisions of gas-phase molecules with the wall.

Constructor & Destructor Documentation

◆ DustyGasTransport()

DustyGasTransport ( thermo_t thermo = 0)

default constructor

Parameters
thermoPointer to the ThermoPhase object for this phase. Defaults to zero.

Definition at line 16 of file DustyGasTransport.cpp.

Member Function Documentation

◆ setThermo()

void setThermo ( thermo_t thermo)
virtual

Specifies the ThermoPhase object.

We have relaxed this operation so that it will succeed when the underlying old and new ThermoPhase objects have the same number of species and the same names of the species in the same order. The idea here is to allow copy constructors and duplicators to work. In order for them to work, we need a method to switch the internal pointer within the Transport object after the duplication takes place. Also, different thermodynamic instantiations of the same species should also work.

Parameters
thermoReference to the ThermoPhase object that the transport object will use

Reimplemented from Transport.

Definition at line 30 of file DustyGasTransport.cpp.

References DustyGasTransport::m_gastran, Transport::setThermo(), and Transport::thermo().

◆ transportType()

virtual std::string transportType ( ) const
inlinevirtual

Identifies the Transport object type.

Each derived class should override this method to return a meaningful identifier.

Reimplemented from Transport.

Definition at line 76 of file DustyGasTransport.h.

◆ getMultiDiffCoeffs()

void getMultiDiffCoeffs ( const size_t  ld,
doublereal *const  d 
)
virtual

Return the Multicomponent diffusion coefficients. Units: [m^2/s].

If the transport manager implements a multicomponent diffusion model, then this method returns the array of multicomponent diffusion coefficients. Otherwise it throws an exception.

Parameters
[in]ldThe dimension of the inner loop of d (usually equal to m_nsp)
[out]dflat vector of diffusion coefficients, fortran ordering. d[ld*j+i] is the D_ij diffusion coefficient (the diffusion coefficient for species i due to species j).

Parameters
state1Array of temperature, density, and mass fractions for state 1.
