A modeling strategy for the Thickened Flame simulation of propagating lean hydrogen–air flames

JJ Hok, O Dounia, N Detomaso, T Jaravel… - International Journal of …, 2024 - Elsevier
Even in the laminar regime, lean H 2-air flames are prone to intrinsic Thermo-Diffusive (TD)
instabilities which contribute to flame acceleration. Applying the Thickened Flame (TF) …
