In this study, we carried out a direct numerical simulation of swirling jets to investigate the temporal characteristics of coherent structures related to the vortex breakdown. The type of coherent motion of oscillation, as a temporal characteristic of vortex breakdown, is observed through the analysis of correlation functions. It indicates that the vortex breakdown is accompanied with the resonance...
To predict the particle dispersion in the burner jet is of great importance in industrial application and in the designing of coal burner with good performance. The objective of this study was to numerically investigate the particle dispersion mechanisms in the gas–solid two-phase jet from a fuel rich/lean burner. The detached-eddy-simulation (DES) approach was employed to study the turbulent flow...
The flow field of a rectangular exit, semi-confined and submerged turbulent jet impinging orthogonally on a flat plate with Reynolds number 8500 was studied by large eddy simulation (LES). A dynamic sub-grid stress model has been used for the small scales of turbulence. The evolvements such as the forming, developing, moving, pairing and merging of the coherent structures of vortex in the whole regions...
