Rules governing flame propagation in fuel-deficient hydrogen-air mixtures in cylindrical reactors

Abstract

The special features of flame propagation in hydrogen⎯air mixtures with low hydrogen contents in horizontal cylindrical reactors with different diameters were studied. The dependences of the lower con centration limit of flame propagation and flame propagation velocity on the diameter of reactors and the chemical properties of the surface were determined. The character of the dependence of the flame cellular structure on mixture composition and reactor diameter was studied.
