Shock wave focusing is an effective way to create a hot spot or a high-pressure and high-
temperature region at a certain place, showing its unique usage in detonation initiation …

Hydrogen is a key pillar in the global Net Zero strategy. Rapid scaling up of hydrogen
production, transport, distribution and utilization is expected. This entails that hydrogen …

The sensitivity to detonation of ammonia-oxygen (NH 3-O 2) and ammonia-nitrous oxide
(NH 3-N 2 O) mixtures has been investigated experimentally and numerically. Detonation …

The induction zone length is an important length scale for gaseous detonations, as it is
correlated with other characteristic parameters such as the cell size. A good characterization …

The present work reports new experiments of detonation diffraction in a 2D channel
configuration in stoichiometric mixtures of ethylene, ethane, and methane with oxygen as …

This investigation concerns the problem of detonation attenuation in stoichiometric methane-
oxygen and its re-establishment following its interaction with obstacles, using high resolution …

The critical tube diameter problem for quasi-detonations is studied via experiments and two-
dimensional numerical simulations based on the reactive Euler equations. In the …

Abstract Large Eddy Simulations (LES) are a powerful tool to analyze the flow in Rotating
Detonation Engines, but their implementation is not straightforward. Many groups use …

The effect of chemistry modeling on the flow structure and quenching limits of detonations
propagating into reactive layers bounded by an inert gas is investigated numerically. Three …

Previous studies have demonstrated the effective enhancement of initiation stability in the
combustor of a rotating detonation engine through the use of a pre-detonator. However …
