Abstract

The local reaction zone thicknesses of high intensity turbulent premixed flames, whose Kolmogoroff scale is smaller than a laminar premixed flame thickness have been examined for various mixture ratios by using a microelectrostatic probe with two identical sensors. For a wide range of mixture ratios, the local reaction zone thickness of high intensity turbulent premixed flame is similar to the laminar premixed flame thickness. It is presumed that even in intense turbulence, small scale turbulent eddies may not survive in the local reaction zone. The inner structure of a laminar premixed flame would be preserved at the local reaction zone of turbulent premixed flames.
