Studies of the Mechanism of Flame Propagation in Premixed Gases

Abstract

AbstractThe steady‐state equations for the conservation of mass, energy and chemical species through an infinite plane flame front are set down and their complete solution discussed. If a solution is attempted, lack of information regarding high‐temperature reaction kinetics is a serious handicap at present. It is concluded that a practicable approach to the problem can be based upon simultaneous measurements of burning velocity with temperature and/or species concentration distributions through the flame‐front. Progress in the optical measurement of temperature distribution and its interpretation in the direction of flame reaction kinetics is reported. Examples are given of the use of simplified methods of interpretation for purposes of comparative flame studies in connection with the use of gaseous and particulate flame inhibitors.
