A One-Dimensional Flux-Corrected Transport Code for Detonation Calculations

Abstract

The development of a one-dimensional Flux-Corrected Transport code to model detonation in a homogeneous medium is described. The material flow is modelled using the Euler equations, and the chemical kinetics by a two-step induction parameter model which uses a quasi-steady induction time and first order Arrhenius kinetics. Two different modes off initiation are compared. Conditions necessary for a self-sustaining detonation are described and illustrated. A detailed comparison is made between the variable profiles calculated by the code and those calculated analytically using the simple Chapman-Jouguet theory and self-similar analysis, and the overall agreement is excellent. The effect of the computational cell size on these solutions is also considered.
