Accurate modeling of flame-wall interaction is essential for predicting premixed hydrogen combustion in confined configurations relevant to hydrogen-based energy systems. Detailed chemical mechanisms often produce unphysical near-wall heat release due to persistent radical-consuming reactions at low temperatures, reducing simulation fidelity and limiting predictive capability. To address this, we apply an H radical recombination model that selectively removes H radicals at the wall through recombination to $\ce{H2}$ while conserving mass. The model is validated using canonical flame-wall interaction scenarios, including head-on quenching of stoichiometric hydrogen/oxygen flames and side-wall... More >
