Abstract
It is well-known that turbulent wake flow behind the grating which consists of fine cylindrical rods has many eddies with a uniform scale particular to the rod diameter, and exhibits a dominant peak in the frequency spectrum of the velocity fluctuation. In this investigation the behavior of the turbulent premixed flame propagating in such a intense turbulent wake flow without mean, which is produced by a high speed motion of the grating of about lOm/s in stagnant premixed gas, are optically examined using tomography technique. It is first shown that, in the case without motion of the grating, a smooth and spherically-propagating laminar flame is observed in the stagnant mixture. In the intense turbulent wake flow without combustion, many eddies with a uniform scale are clearly distinguished, and a corrugated flame front propagating radially is clearly observed in the case with combustion. Keywords: Combustion, Turbulent Premixed Flame, Flame Structure, Tomography Diagnostics, Fine and Intense Turbulence
