LES of a bluff-body stabilised turbulent premixed flame using FSD transport equation

What is it about?

In turbulent premixed combustion, the fluctuating velocity field wirinkles the flame and increase its area. This effect is described by the flame surface density (FSD). In this paper, information on the FSD production by hydrodynamic straining and FSD destruction by propagation and curvature effects are shown for the first time in LES using the FSD transport equation for a premixed flame in an afterburner-like configuration.
