The Deflagration-to-Detonation Transition

摘要

Time-dependent multidimensional solutions of the Navier-Stokes equations were used to study the processes leading to the transition from a deflagration to a detonation in an energetic reactive gas mixture. This paper describes selected phenomena observed in the simulations and relates these to the development of hot spots (ignition centers) and spontaneous reaction waves arising in gradients of reactivity.
