The AVBP code is a parallel code of fluid mechanics that solves compressible Navier-Stokes equations for laminar and turbulent reactive flows, in 2D and 3D, on unstructured and hybrid meshes, with third order Taylor Galerkin schemes. The resolution of these equations is based on the Large Eddy Simulation (or Large Eddy Simulation) approach. Reduced chemical kinetics according to the Arrhenius law coupled to the TFLES model for sub-grid flame-turbulence interactions make possible to treat combustion phenomena. AVBP can also calculate two-phase flows using a Lagrangian or Eulerian solver. AVBP applies to aeronautical combustion chambers, turbomachinery, industrial furnaces and safety issues, it allows for example to evaluate polluting emissions (CO, NOx and soot), to treat thermo-acoustic instabilities or detonation phenomena. AVBP is a world-famous code in the field of combustion, used by many laboratories (IMFT in Toulouse, EM2C in Centralesupelec, TU Munich, Von Karmann Institute, ETH Zurich, etc.) and in industry (SAFRAN AIRCRAFT ENGINES, SAFRAN HELICOPTER ENGINES, ARIANEGROUP, HERAKLES, TOTAL, etc.).
