This work is part of the exaFOAM project that aims to enable the open-source CFD software OpenFOAM to exploit massively parallel HPC architectures and overcome performance scaling bottlenecks. The case is based on the experiment carried out by Pitz and Daily 1983, who measured a combustion flow formed at a backward facing step. The goal of the work was to study the turbulent shear layer during a combustion process in conditions similar to those of the industrial and aircraft gas turbine combustors. The premixed combustion is stabilized by recirculation of hot products which are mixed with cold reactants in a turbulent shear layer. The setup with a backward facing step is one of the simplest configurations reproducing these conditions. Detailed information and case setup can be found in the README.md file contained in the case setup file.
