fluide_incompressible
Inherits from: fluide_base
Class for non-compressible fluids.
Parameters:
- [beta_th] (type: field_base) Thermal expansion (K-1).
- [mu] (type: field_base) Dynamic viscosity (kg.m-1.s-1).
- [beta_co] (type: field_base) Volume expansion coefficient values in concentration.
- [rho] (type: field_base) Density (kg.m-3).
- [cp] (type: field_base) Specific heat (J.kg-1.K-1).
- [lambda_ | lambda] (type: field_base) Conductivity (W.m-1.K-1).
- [porosites] (type: bloc_lecture) Porosity (optional)
- [indice] (type: field_base) Refractivity of fluid.
- [kappa] (type: field_base) Absorptivity of fluid (m-1).
- [diametre_hyd_champ] (type: field_base) Hydraulic diameter field (optional).
- [porosites_champ] (type: field_base) The porosity is given at each element and the porosity at each face, Psi(face), is calculated by the average of the porosities of the two neighbour elements Psi(elem1), Psi(elem2) : Psi(face)=2/(1/Psi(elem1)+1/Psi(elem2)). This keyword is optional.
- [gravite] (type: field_base) Gravity field (optional).
fluide_ostwald
Inherits from: fluide_incompressible
Non-Newtonian fluids governed by Ostwald\'s law. The law applicable to stress tensor is:
tau=K(T)*(D:D/2)**((n-1)/2)*D Where:
D refers to the deformation tensor
K refers to fluid consistency (may be a function of the temperature T)
n refers to the fluid structure index n=1 for a Newtonian fluid, n<1 for a rheofluidifier fluid, n>1 for a rheothickening fluid.
Parameters:
- [k] (type: field_base) Fluid consistency.
- [n] (type: field_base) Fluid structure index.
- [beta_th] (type: field_base) Thermal expansion (K-1).
- [mu] (type: field_base) Dynamic viscosity (kg.m-1.s-1).
- [beta_co] (type: field_base) Volume expansion coefficient values in concentration.
- [rho] (type: field_base) Density (kg.m-3).
- [cp] (type: field_base) Specific heat (J.kg-1.K-1).
- [lambda_ | lambda] (type: field_base) Conductivity (W.m-1.K-1).
- [porosites] (type: bloc_lecture) Porosity (optional)
- [indice] (type: field_base) Refractivity of fluid.
- [kappa] (type: field_base) Absorptivity of fluid (m-1).
- [diametre_hyd_champ] (type: field_base) Hydraulic diameter field (optional).
