Rheological and thermodynamic behavior of fluid
Description of the fluid module
The fluid module module_fluid_law proposes different rheological and thermodynamic laws for the fluids.
Fluid type
In the current version, three fluid types are proposed:
incompressible liquid
perfect gas
mixture of liquid and gaz
The fluid parameters are:
ρ 0
r g
λ
Density and compressibility
The module is limited to the density ρ rho and compressibility
∂ ρ ∂ p drhodp computation based on the pressure p t
Incompressible INC
Perfect gas GP
ρ = 1 1 − λ ρ 0 + λ r g T p
∂ ρ ∂ p = λ ρ 2 O r g T ( p ( 1 − λ ) + λ r g T ρ 0 ) 2

Solid arrows point from a submodule to the (sub)module which it is
descended from. Dashed arrows point from a module or program unit to
modules which it uses. Where possible, edges connecting nodes are given different colours to make them easier to distinguish in large graphs.
