Cover Story: The reactive scalar gradient magnitude is of pivotal importance in the fundamental understanding and modeling of turbulent reacting flows because of its relevance to surface area density and scalar dissipation rate (and thus impacts micro-mixing). The statistical behaviors of the different timescales associated with the flame normal strain rate and flame normal gradients of chemical reaction rate and molecular diffusion rate, which appear in the transport equation of the fractional change in the reactive scalar gradient magnitude, have been analyzed in this study. The analysis has been conducted using 3D direct numerical simulation data of statistically planar turbulent premixed flames ranging from the corrugated flamelets regime to the thin reaction zones regime to elucidate the effects of the combustion regime on the aforementioned timescales. View this paper
