High-resolution numerical simulations of cellular detonations are performed using a parallelized adaptive grid solver, in the case where the channel width is very wide. In particular, the nonlinear response of a weakly unstable Zeldovich–Neumann–Doering (ZND) detonation to two-dimensional perturbations is studied in the context of the idealized one-step chemistry model. For random perturbations, cells appear with a characteristic size in good agreement with that corresponding to the maximum… 

Numerical Simulation of Cellular Structure of Weak Detonation and Evaluation of Linear Stability Analysis Predictions

Abstract This paper investigates the development of cellular structures created by the propagation of a detonation wave in a gaseous mixture. Two dimensional reactive Euler equations with an

Numerical Study of Gaseous Detonation Propagation Across a Density Interface

The transient, multi-dimensional cellular structure of the detonation has been well observed both experimentally and numerically [1]. However, due to various instability features and interaction

Statistical analysis of cellular detonation dynamics from numerical simulations: one-step chemistry

In this paper, two methods are developed for statistically analysing the nonlinear cellular dynamics from numerical simulations of gaseous detonations, one use of which is the systematic

Numerical study on unstable surfaces of oblique detonations

Abstract In this study, the onset of cellular structure on oblique detonation surfaces is investigated numerically using a one-step irreversible Arrhenius reaction kinetic model. Two types of oblique

Numerical Simulations of Detonation Re-initiation Behind an Obstacle

This numerical study explored the mechanisms responsible for the re-initiation of a detonation, which quenched while diffracting over a half-cylinder obstacle. The purpose of the study was to make

Multiplicity for idealized rotational detonation waves

Simulations of three-dimensional rotational detonation waves are conducted to understand the mechanisms of wave bifurcation. A compressible reacting Euler solver is developed within the framework of
