Mathematical Analysis of Reactive Multiphase Flows
Abstract
This work provides a mathematical analysis of a reactive multiphase flow model introduced by Baer and Nunziato in their studies of deflagration-to detonation transition (DDT) in reactive granular materials. This work combines asymptotic methods with numerical computations and theoretical analysis. In particular, we derive an asymptotic model to explain the formation and growth of hot spots during DDT in reactive granular materials. The model is founded on nonlinear geometrical optics and high energy asymptotics near choked flow states. Through analysis and numerical simulations, the model is able to reproduce several of the scenarios for DDT previously documented in the literature for the continuum model of Baer and Nunziato.
