abstract
By using a glass tube into which a combustible mixture is tangentially injected from one end, the behavior of flames in vortex flow, especially the flame shapes and the flame forming range in fuel concentrations, has been experimentally investigated. To improve the controllability of combustion, an iris diaphragm is inserted in the tube. The results show that a tubular flame with a constant diameter is formed near the lean flammability limit, and that the combustion range in the concentration extends with an increase of the inner diameter in the glass tube. When the iris diaphragm is inserted, the flame changes into spindle- or bugle-shaped, and the length of the tubular flame is shortened with its extinction characteristics unchanged.
