A staggered arrangement of solid obstacles promotes flame acceleration (FA) and the deflagration-to-detonation transition (DDT) in a homogeneous concentration field. Many combustible premixed gases, however, are inhomogeneous. The present numerical study explores effects different hydrogen–air distributions on FA DDT processes obstacle-laden channel. results show that, early stage evolution, accelerates faster when there no obstructions side channel with high hydrogen concentration. Under...
This study conducts a detailed numerical investigation on the spatial distribution of solid obstacles using large eddy simulation method. It is discovered that although flame acceleration induced by dominated factors such as flow field disturbances, vortices and recirculation zones, turbulence, surface areas combustion heat release rates, etc., characteristics leading shock wave are key to detonation initiation. Specifically, intensity wave, its formation time, distance from front...
Due to the complexity and short timescale of detonation, it is usually difficult capture its transient characteristics experimentally. Advanced numerical methods are essential for enhancing understanding flow field structure combustion mechanism detonation. In this study, a density-based compressible reactive solver called CDSFoam developed simulating gas-droplet two-phase detonation based on OpenFOAM. The primary feature implementation two-way coupling between gas liquid phases, utilizing...
Fluidic obstacles, employed as a form of turbulence generator, are often utilized to facilitate flame acceleration and deflagration-to-detonation transition (DDT). This paper conducts detailed numerical study focusing on the position (L1) delayed injection time. The results indicate that reducing L1 leads an earlier interaction between vortex structures, thus enhancing initial effect. However, this also in reduction movement which prevents enhancement intensity within channel. Conversely,...
