Numeric simulation and analysis of H2-O2 premixed combustion based on OpenFOAM

OpenFOAM is one open source CFD software, reactingFoam is the solver for chemistry and combustion. Cantera is a software tools for problems involving chemical kinetics, thermodynamics, and transport processes. So the coupling of OpenFOAM and Cantera can provide better simulation of combustion than the solver reactingFoam in OpenFOAM. In this context, we couple OpenFOAM and Cantera, and calculate the same H₂-O₂ premixed combustion case with steady solver coupled with Cantera and different transient solvers coupled and not coupled with Cantera. Through the comparison and analysis of different calculations results of the same case, we can see that solvers coupled with Cantera based on OpenFOAM produce more precision result that solver reactingFoam does in deed, and in general, transient solver can reveal more precision trend than steady solver with higher time consumption.
