| Abstract: | In this work, a numerical methodology based on the geometric approach and turbulent flame closure (TFC) has been applied to simulate weak and strong flame acceleration in hydrogen-air mixtures. Flame tracking is based on the transport equation for the progress variable. To minimize the need for tuning/calibration of model parameters, a generalized transport equation for the flame-wrinkling factor is adopted rather than algebraic closure models. Turbulence modeling was based on Reynolds-averaged Navier–Stokes (RANS). For sharp resolution of shocks, a density-based solver has been adopted. The open-source toolbox OpenFOAM has been used to perform all numerical simulations. A relatively coarse spatial discretization has been employed to enable application to larger domains. A detailed validation study has been carried out for the SSEXHY shock tube facility. For the range of hydrogen concentrations considered, a good prediction of the trend in flame speed has been obtained. The model can capture both weak and strong flame acceleration, as well as their transition, without requiring any model switching or parameter tuning. [ABSTRACT FROM AUTHOR] |
