Abstract : A generic problem in the transition from deflagration to detonation is the overtaking of a steady deflagration wave by a steady shock wave. Such a collision produces a detonation wave (as well as a contact discontinuity, a back shock, and sometimes a rarefaction wave). Work reported at the 27th Conference of Army Mathematicians showed that, for small heat release in the deflagration, the detonation wave cannot be steady. Here we remove the restriction to small heat release and show that the detonation wave can never be steady. (Author)
