Numerical Investigation of Turbulent Flame Sheets
Abstract
An accurate physical model of a premixed turbulent flame (in the flamelet regime) is that combustion is confined to a thin sheet that can be regarded as a mathematical surface. This surface is convected and bent by the fluid motion, and it propagates normal to itself (relative to the fluid) at the local laminar flame speed. Direct numerical simulations have been performed to examine the important properties of material (i.e. non-propagating) and propagating surfaces in turbulence. The results have been described in seven papers. The straining, curvature and cusp formation of these surfaces has been well characterized.
