Abstract

In this study, a reacting flow solver with detailed transport, chemistry and steady-state preserving splitting schemes based on OpenFOAM (OF) and Cantera is developed. To address the existing issues in the current OF platform, Cantera package is coupled with OF so that the chemistry reader, chemistry model and species transport properties handled by Cantera could be accessed by OF. In this way, the simplified transport model and inaccurate ordinary differential equation (ODE) solver in OF can be replaced by the more detailed transport model and reliable CVODE solver. More importantly, two steady-state preserving splitting schemes are implemented in this new solver, showing better accuracy than the existing OF splitting way. The newly added features in this new solver is assessed and validated with a series of auto-ignition, unsteady perfectly stirred reactor and counter flow diffusion flame cases.
