- Abstract
- Leading edge statistics are obtained by direct numerical simulation (DNS) of freely propagating incompressible and stagnating compressible turbulent premixed flames. Conditional averages of velocities in terms of reaction progress variable, , and local flame surface density, , are defined and compared through the flame brush. It holds asymptotically that and with the characteristic length scale of variation, . It also holds that for a freely propagating flame under no mean strain rate. The turbulent burning velocity, ST, is determined by the conditional statistics at the leading edge under large activation energy.
