24 Class
25  Foam::laminarThermophysicalTransportModels::FickianFourier
26 
27 Description
28  Multi-component Fickian and Fourier based temperature gradient heat flux
29  models with optional Soret thermal diffusion of species for laminar flow.
30 
31  The mixture diffusion coefficients are specified as Function2<scalar>s of
32  pressure and temperature but independent of composition.
33 
34  The heat flux source is implemented as an implicit energy correction to the
35  temperature gradient based flux source. At convergence the energy
36  correction is 0.
37 
38 Usage
39  \verbatim
40  laminar
41  {
42  model FickianFourier;
43 
44  mixtureDiffusionCoefficients yes;
45 
46  Dm // [m^2/s]
47  {
48  O2 1e-2;
49  O3 5e-2;
50  N2 1e-2;
51  }
52 
53  DT // [kg/m/s] Optional
54  {
55  O2 1e-2;
56  O3 5e-2;
57  N2 1e-2;
58  }
59  }
60  \endverbatim
61 
62  or if binary mass diffusion coefficient functions are available they can be
63  mixed to form the mass diffusion coefficients w.r.t. the mixture:
64 
65  \verbatim
66  laminar
67  {
68  model FickianFourier;
69 
70  mixtureDiffusionCoefficients no;
71 
72  D // [m^2/s]
73  {
74  O2-O2 1e-2;
75  O3-O3 5e-2;
76  N2-N2 1e-2;
77  O3-O2 5e-2;
78  O3-N2 5e-2;
79  O2-N2 1e-2;
80  }
81 
82  DT // [kg/m/s] Optional
83  {
84  O2 1e-2;
85  O3 5e-2;
86  N2 1e-2;
87  }
88  }
