The performance of rotating detonation engines is strongly affected by the multiple
detonation waves that occur, although the reason for their formation has not yet been fully …

High-speed schlieren visualization and numerical simulations are used to study the fluid
mechanics following a spark discharge and the effect on the ignition process in a hydrogen …

In the present work the propagating modes of detonation wave in supersonic hydrogen–air
mixtures are investigated in narrow rectangular channels. To clarify the effect of the …

The fluidic jet turbulator has been a novel perturbation generator in the pulse-detonation
engines research field for the past few years. In this paper, an experiment is performed to …

The present study addresses the reaction zone structure and burning mechanism of
unstable detonations. Experiments investigated mainly two-dimensional methane–oxygen …

Transient jet flame propagation under newly proposed multistage pre-chambers is studied in
a constant-volume combustion chamber with a high-speed schlieren photography system …

This paper presents the development of a discontinuous Galerkin (DG) method for
application to chemically reacting flows in subsonic and supersonic regimes under the …

Experiments conducted over the past several decades have shown that the cellular structure
of detonations is responsible for enhancing the detonability of gaseous detonations in the …

The present manuscript reports a numerical verification study based on a series of tests that
allows to evaluate the numerical performance of a compressible reactive multicomponent …

The main objective of this work is to comprehensively provide a fundamental understanding
of the entire process of the flame-pressure wave interactions with end-gas autoignition and …
