Abstract: A combination of microgravity experiments and computational simulations were used to study effects of diluents on the near-limit properties of laminar, premixed hydrogen/air flames. The experiments were conducted in a short-drop free-fall laboratory facility that provided at least 450 ms of 10 −2 g conditions. Outwardly propagating spherical flames were used to measure near-limit laminar burning velocities at various fuel-equivalence ratios and pressures with reactants containing varying concentrations of He,…
