Code Saturne
Encyclopedia
Code_Saturne is a general purpose computational fluid
dynamics
free software. Developed since 1997 at EDF
R&D, Code_Saturne is distributed under the GNU GPL licence.
It is based on a co-located Finite Volume
approach that accepts meshes with any type of cell (tetrahedral, hexahedral, prismatic, pyramidal, polyhedral…) and any type of grid structure (unstructured, block structured, hybrid, conforming or with hanging nodes…).
Its basic capabilities enable the handling of either incompressible or expandable flows with or without heat transfer and turbulence (mixing length, 2-equation models, v2f, Reynolds stress models
, Large eddy simulation
…).
Dedicated modules are available for specific physics such as radiative heat transfer, combustion (gas, coal, heavy fuel oil, …), magneto-hydro dynamics, compressible flows, two-phase flows
(Euler-Lagrange approach
with two-way coupling), extensions to specific applications (e.g. for atmospheric environment).
Code_Saturne can be coupled to thermal software SYRTHES for conjugate heat transfer. It can also be used jointly with structural analysis software Code Aster
, in particular in the Salomé platform. SYRTHES and Code_Aster are developed by EDF and distributed under the GNU GPL licence.

Computational fluid dynamics
Computational fluid dynamics, usually abbreviated as CFD, is a branch of fluid mechanics that uses numerical methods and algorithms to solve and analyze problems that involve fluid flows. Computers are used to perform the calculations required to simulate the interaction of liquids and gases with...

Finite volume method
The finite volume method is a method for representing and evaluating partial differential equations in the form of algebraic equations [LeVeque, 2002; Toro, 1999]....

Reynolds stresses
In fluid dynamics, the Reynolds stress is the stress tensor in a fluid obtained from the averaging operation over the Navier-Stokes equations to account for turbulent fluctuations in fluid momentum.-Definition:...
, Large eddy simulation
Large eddy simulation
Large eddy simulation is a mathematical model for turbulence used in computational fluid dynamics. It was initially proposed in 1963 by Joseph Smagorinsky to simulate atmospheric air currents, and many of the issues unique to LES were first explored by Deardorff...

Multiphase flow
In fluid mechanics, multiphase flow is a generalisation of the modelling used in two-phase flow to cases where the two phases are not chemically related or where more than two phases are present In fluid mechanics, multiphase flow is a generalisation of the modelling used in two-phase flow to...
(Euler-Lagrange approach
Lagrangian and Eulerian coordinates
In fluid dynamics and finite-deformation plasticity the Lagrangian specification of the flow field is a way of looking at fluid motion where the observer follows an individual fluid parcel as it moves through space and time. Plotting the position of an individual parcel through time gives the...
