摘要:

Computed vorticity-flame interactions in two-dimensions suggest that a wrinkled flame is a common occurrence in reacting turbulent flow and that these wrinkles are formed in a small fraction of an eddy turn-over time. An experiment in which the Tsuji porous-cylinder burner is spinning may be a way to achieve a steady, wrinkled diffusion flame under laboratory conditions. The wrinkled flame differs from the previously studied stagnation, counterflow flame in that the former has a large spatial variation in diffusive gradients near the wrinkle. These gradient variations may explain the extinction observed in unsteady, pulsed jets by Lewis et al
