| Code_Saturne, SALOME & NEPTUNE_CFD
Code_Saturne is an open source, 3D general Computational Fluid Dynamics (CFD) solver with excellent parallel capabilities. Based on a co-located finite volume scheme for unstructured meshes and mostly focused on incompressible flows, it has been developed since 1997 and distributed under a free software GPLV2 license since 2007. It features several turbulence models, from Reynolds-Averaged models to Large-Eddy Simulation models. In addition, a number of specific physical models are also available as modules, including combustion, semi-transparent radiative transfer, Lagrangian particle-based modelling, electrics arcs, atmospheric flows and rotor/stator interaction for hydraulic machines.
SALOME is an open-source software that provides a generic Pre- and Post-Processing platform for numerical simulation in various scientific domains. The platform provides one single simulation environment for a wide range of complex industrial systems such as solid mechanics, structural dynamics, fluid physics, thermohydraulics, nuclear physics, radiations or electromagnetism.
NEPTUNE_CFD, a solver powered by Code_Saturne, can simulate a wide variety of multiphase flows: free-surface flows and dispersed flows with closures to model the inter-phase transfers. There are dedicated model which can simulate regime transitions of two-phase flows (from dispersed to stratified two-phase flows). The solver, based on the Eulerian approach, can be embedded in the SALOME platform and is a joint R&D initiative involving giants of the French civil nuclear industry (CEA, EDF, FRAMATOME, IRSN) to develop the next-generation of simulation tools for nuclear thermal-hydraulics.
| Code_Saturne, a versatile open source code!
Whilst the open source CFD code Code_Saturne was born in the nuclear industry and is still actively developed for the entire nuclear chain, its large range of validated models along with the pre and post processing platform SALOME_CFD make it the perfect 3D general CFD tool for for many applications, some of which are showcased here.
| Projects
| Combustion for power generation
In conjunction with SALOME for CAD and volume meshing, SYRTHES for conjugate heat transfer and ParaView for results analysis, Code_Saturne was successfully used to simulate combined coal and biomass power plant simulations (including the effects of heat exchangers) to assess the impact of biomass for three models: Eulerian, Lagrangian, and Eulerian.
| Water filtering system
Veolia, a global leader in optimized resource management, has a range of water filtering system products that use carbon pellets to filter raw water. During the development phase field tests indicated that the Filtraflo® range of products were not operating as desired. Renuda was asked to perform simulations which aimed of homogenising the velocity field in the main tank in order to improve the efficiency of the filtering system.
| Combustion system simulation
Fives designs machines, process equipment and production lines for the world’s largest industrial sectors, one such system uses exhaust gas to heat incoming air for combustion and to entrain burnt gas into the combustion process. To keep costs down Fives Stein asked Renuda to simulate three systems using different nozzle sizes to determine which design to test experimentally. Simulations were carried out using SALOME, Code_Saturne and SYRTHES.
