ABSTRACT
A coherent flame model (CFM) has been implemented into the large eddy simulation (LES) frame of the OpenFOAM® code, which is the Open Source CFD Toolbox developed and maintained by OpenCFD Limited [1]. The code with the CFM as well as the two equation turbulent deflagration model implemented by OpenFOAM developer has been applied to simulate propane spherical flame, hydrogen-air and propane-air flame acceleration in obstructed channels. The study has demonstrated the capability of the code for such application, its potential for further development as well as the limitation of the current version of the code and the CFM approach for the more unstable hydrogen deflagration and wall-flame interaction.
Keywords: CFD, Open source, OpenFOAM, Deflagration, Detonation, Coherent flame model.
