The treatment of inlet conditions for LES is a complex problem, but of extreme importance
as, in many cases, the fluid behaviour within the domain is determined in large part by the …

The interaction of a helical precessing vortex core (PVC) with turbulent swirl flames in a gas
turbine model combustor is studied experimentally. The combustor is operated with air and …

Numerical computation methods are used more and more as tools for solving hydraulic and
environmental engineering problems, and as turbulence mostly plays an important role in …

In this paper, we study the shape and dynamics of helical coherent structures found in the
flow field of an annular swirling jet undergoing vortex breakdown. The flow field is studied by …

Transverse acoustic instabilities in premixed, swirl-stabilized flames are an important
problem in low NOx combustors. Transverse excitation of swirling flames involves complex …

This paper studies the coherent structures found in an annular swirling jet flow undergoing
vortex breakdown with control parameters, the Reynolds number Re= 8500 and the swirl …

Compared to the traditional modeling of computational fluid dynamics, direct numerical
simulation (DNS) and large-eddy simulation (LES) provide a very detailed solution of the …

This paper presents bifurcation analyses characterising the nonlinear dynamics of fully
developed laminar annular jets with respect to the centrebody diameter is increased …

In this paper, we investigate the flow structures and pressure fields of a free annular swirling
jet flow undergoing vortex breakdown. The flow field is analyzed by means of time-resolved …

This paper presents an extensive study of the influence of swirl on the initial region of an
annular jet. A total of five different swirl numbers S are investigated: one at zero swirl, one at …
