This book was released on 2013 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Detonation waves are supersonic combustion waves that have a multi-shock front structure followed by a spatially non-uniform reaction zone. During propagation, a de-coupled shock-flame complex is periodically re-initiated into an overdriven detonation following a transient Mach reflection process. Past researchers have identified mechanisms that can increase combustion rates and cause localized hot spot re-ignition behind the Mach shock. But due to the small length scales and stochastic behaviour of detonation waves, the important mechanisms that can lead to re-initiation into a detonation requires further clarification. If a detonation is allowed to diffract behind an obstacle, it can quench to form a de-coupled shock-flame complex and if allowed to form a Mach reflection, re-initiation of a detonation can occur. The use of this approach permits the study of re-initiation mechanisms reproducibly with relatively large length scales. The objective of this study is to experimentally elucidate the key mechanisms that can increase chemical reaction rates and sequentially lead to re-initiation of a de-coupled shock-flame complex into an overdriven detonation wave following a Mach reflection. All experiments were carried out in a thin rectangular channel using a stoichiometric mixture of oxy-methane. Three different types of obstacles were used - a half-cylinder, a roughness plate along with the half-cylinder and a full-cylinder. Schlieren visualization was achieved by using a Z-configuration setup, a high speed camera and a high intensity light source. Results indicate that forward jetting of the slip line behind the Mach stem can potentially increase combustion rates by entraining hot burned gas into unburned gas. Following ignition and jet entrainment, a detonation wave first appears along the Mach stem. The transverse wave can form a detonation wave due to rapid combustion of unburned gas which may be attributed to shock interaction with the unburned gas. Alternatively, the Kelvin-Helmholtz instability can produce vortices along the slipline that may lead to mixing between burned-unburned gases and potentially increase combustion rates near the transverse wave. However, the mechanism(s) that causes the transverse wave to re-initiate into a detonation wave remains to be satisfactorily resolved.

Available in PDF, EPUB and Kindle. Book excerpt: The major portion of this report is devoted explicitly to the study of the standing detonation wave in a hydrogen-air mixture. The experimental arrangement and procedures employed are briefly described and the experimental results presented. A revised analysis of the ignition delay zone behind the shock is presented which handles the equations more rigorously than an earlier treatment. The prediction of the time rate of growth of concentrations of the radicals behind the shock is found to be slightly different than an earlier analysis but the prediction of ignition time delay is unchanged. Vibrational relaxation is considered insofar as it affects the ignition time delay. Preliminary measurements aimed at probing the combustion region of the detonation wave by means of a sodium D-line reversal technique are described. A consideration of some probable two dimensional effects behind the shock reveal a likely explanation of some hitherto uncertain anomalous ignition delay measurements.
