Wave structure of marginal detonations, propagated through nitrogen-diluted stoichiometric hydrogen-oxygen mixtures in a 1-3/4 in. by 3/4 in. rectangular tube, is studied by the soot technique and velocity probes. Both weak shocks and strong detonations are shown to propagate transversely behind the detonation front. In marginal detonations in rectangular tubes, waves propagate in both lateral directions behind the initial shock. Ordinarily, each wave is the weak reflected shock of a triple shock interaction. Occasionally, however, as the result of a complex shock interaction, a transverse detonation is developed behind the leading shock. This produces a trace in the form of a band on a tube wall that has been previously coated with carbon soot. The width of this band is governed by the induction delay behind the initial shock. By coupling its measurement with velocity data, induction times and temperatures are obtained from self-sustained detonations. (Author).

Comprehensive review of detonation explores the "simple theory" and experimental tests of the theory; flow in a reactive medium; steady detonation; the nonsteady solution; and the structure of the detonation front. 1979 edition.

This book, as a volume of the Shock Wave Science and Technology Reference Library, is primarily concerned with the fundamental theory of detonation physics in gaseous and condensed phase reactive media. The detonation process involves complex chemical reaction and fluid dynamics, accompanied by intricate effects of heat, light, electricity and magnetism - a contemporary research field that has found wide applications in propulsion and power, hazard prevention as well as military engineering. The seven extensive chapters contained in this volume are: - Chemical Equilibrium Detonation (S Bastea and LE Fried) - Steady One-Dimensional Detonations (A Higgins) - Detonation Instability (HD Ng and F Zhang) - Dynamic Parameters of Detonation (AA Vasiliev) - Multi-Scaled Cellular Detonation (D Desbordes and HN Presles) - Condensed Matter Detonation: Theory and Practice (C Tarver) - Theory of Detonation Shock Dynamics (JB Bdzil and DS Stewart) The chapters are thematically interrelated in a systematic descriptive approach, though, each chapter is self-contained and can be read independently from the others. It offers a timely reference of theoretical detonation physics for graduate students as well as professional scientists and engineers.
