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).

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).
