Experimental study and theoretical analysis of a 'strange wave'

摘要

Alexei Khokhlov, Geraint Thomas and co-authors have identified a strong coupling of shock and reaction front different from detonation and named it Strange Wave. In spite of the strong coupling, a Strange Wave exhibits an over-pressure and a velocity appreciably smaller than detonation. Experimental evidence that allows for the identification of such a 'strange wave' with a quasi-stationary strong shock followed by a funnel formed flame is presented herein. Such a structure is subsequently analyzed with a method similar to the one applied to detonation in the Simplest Theory. The method followed is based on Rankine-Hugoniot relations connected with the flame propagation conditions. (C) 2016 The Combustion Institute. Published by Elsevier Inc. All rights reserved.
