Keywords derived from fluide_incompressible

fluide_quasi_compressible

Inherits from: fluide_base

Quasi-compressible flow with a low mach number assumption; this means that the thermo- dynamic pressure (used in state law) is uniform in space.

Parameters:

[sutherland] (type: bloc_sutherland) Sutherland law for viscosity and for conductivity.
[pression] (type: float) Initial thermo-dynamic pressure used in the assosciated state law.
[loi_etat] (type: loi_etat_base) The state law that will be associated to the Quasi-compressible fluid.
[traitement_pth] (type: string into ['edo', 'constant', 'conservation_masse']) Particular treatment for the thermodynamic pressure Pth ; there are three possibilities: 1) with the keyword \'edo\' the code computes Pth solving an O.D.E. ; in this case, the mass is not strictly conserved (it is the default case for quasi compressible computation): 2) the keyword \'conservation_masse\' forces the conservation of the mass (closed geometry or with periodic boundaries condition) 3) the keyword \'constant\' makes it possible to have a constant Pth ; it\'s the good choice when the flow is open (e.g. with pressure boundary conditions). It is possible to monitor the volume averaged value for temperature and density, plus Pth evolution in the .evol_glob file.
[traitement_rho_gravite] (type: string into ['standard', 'moins_rho_moyen']) It may be :1) `standard` : the gravity term is evaluted with rho*g (It is the default). 2) `moins_rho_moyen` : the gravity term is evaluated with (rho-rhomoy) g. Unknown pressure is then P=P+rhomoy*g*z. It is useful when you apply uniforme pressure boundary condition like P*=0.
