The Contribution of A. K. Oppenheim to Explaining the Nature of the Initiation of Gaseous Detonation in Tubes

Abstract This paper analyzes A.K. Oppenheim’s original works on the transition of deflagration to detonation and reviews them from perspective new numerical experimental results recently obtained such phenomena. Particular attention is focused processes happening in boundary layer tube walls ahead accelerating flame. The theoretical analyses temperature variations inside developing are presented compared variation a free stream away layer. Analyses increase layers clearly indicate that self-ignition mixture happens propagating flame front. New by research group A. V. Luikov Heat Mass Transfer Institute Minsk, Belarus, combined with previously conducted simulations, show unambiguously origin “explosion explosion”, postulated K. Oppenheim 1966, always responsible for Deflagration-Detonation Transition (DDT) gases located
