The explosion characteristics of the runaway battery vented gas (BVG) was studied using an
8 L column type device. The effects of ambient temperature, turbulence condition, and …

Solid obstacles induce the detonation in premixed gases while causing significant thrust
losses. Jet obstacles can alleviate this deficiency, but there have been few studies on multi …

Two-dimensional simulations were carried out to investigate the flame acceleration and
deflagration-to-detonation transition (DDT) in a combustion chamber filled with a subsonic or …

Using solid obstacles to accelerate the deflagration to detonation transition (DDT) process
induces additional thrust loss, and fluidic obstacles can alleviate this problem to a certain …

Abstract Jet-in-crossflow (JICF), as a turbulence generator, is proposed to promote the flame
acceleration and deflagration-to-detonation transition (DDT) process. Previous work has …

Abstract The unsteady, reactive Navier-Stokes equations with a detailed chemical
mechanism of 11 species and 27 steps were employed to simulate the mixing, flame …

Gasoline–air mixture explosions mostly occur in buried tank rooms, which are annular
cylindrical confined spaces with circular arches. In this paper, explosion experiments at …

In this study, experiments were performed in a closed duct with a cavity to reveal the effect of
the cavity on the flame propagation behavior. A high-speed camera and three pressure …

In this paper, the detonation initiation mechanism of a supersonic combustible mixture
triggered by a staggered opposing combined hot jets was performed. Two-dimensional …

In the present study, an experimental performance analysis of hollow rotating detonation
engines (RDEs) with Laval nozzles is carried out for the first time. Experiments of a hollow …
