A scaling analysis for the evolution of small-scale turbulence eddies across premixed flames with implications on distributed combustion

In this work, we propose a physics-based scaling theory for the evolution of small-scale turbulence eddies in the unburnt mixture when they travel across the preheat zone of a premixed flame. This scaling theory is developed to explicitly account for the effects of viscous diffusion on the length and velocity scales of turbulence eddies that are smaller than the inner reaction zone thickness of a premixed flame. This scaling suggests that both...
