CERFACS Chemistry Sharing knowledge for CFD chemical kinetics


AVBP is a parallel CFD code that solves the three-dimensional compressible Navier-Stokes on unstructured and hybrid grids, co-developed by CERFACS and IFP-EN. It is used for research and industrial purposes. Understanding the turbulence, especially in reactive flows, requires a balance between calculation time and accuracy, therefore LES (Large-Eddy Simulation) approach was chosen for this code.


If you want to know more about AVBP, go to the AVBP website where you will find some explanations, some examples and some tutorials. If you want to get started, it is advised to start with the 1D flame computation.


This part is dedicated to the use of chemistry in this precise 3D code, used in CERFACS. Indeed, as a strong aeronautical requirement nowadays is to reduce gas emissions from the combustion process, it is needed to look at pollutants such as CO and NOx. Those require to have a sufficiently precise chemistry to be able to predict their concentration, that is why reduced chemistries from ARCANE are included in calculations codes such as AVBP.


You will find in this section :

  • some information about how to include ARC (Analytically Reduced Chemistries) in your calculation.
  • some useful tools that you may use to initialize or analyse the data regarding chemistry.
