- Direct Numerical Simulation (DNS); burning modes (premixed vs. diffusion burning) in autoigniting non-homogeneous mixtures of hydrogen in heated air are studied using direct numerical simulations (DNS); identifying the effects of a non-homogeneous mixture fraction field on the high-temperature combustion modes and the relative contributions of these modes to heat release and the formation of pollutants; summary of initial conditions of the turbulence and scalar fields; high-temperature combustion and burning modes; existence and role of triple flames; contribution of burning modes to overall burning rate and pollutant formation
