In a thermoacoustic system, such as a flame in a combustor, heat release oscillations couple
with acoustic pressure oscillations. If the heat release is sufficiently in phase with the …

The precessing vortex core (PVC) is a coherent flow structure that is often encountered in
swirling flows in gas turbine (GT) combustors. In some swirl combustors, it has been …

The large-scale coherent motions in a realistic swirl fuel-injector geometry are analysed by
direct numerical simulations (DNS), proper orthogonal decomposition (POD), and linear …

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 …

Renewable energy sources (RES) have reached 23.7% of the worldwide electrical
generation production in 2015. The hydraulic energy contribution amounts to 16.6% and …

We study the emergence of precessing vortex core (PVC) oscillations in a swirling jet
experiment. We vary the swirl intensity while keeping the net mass flow rate fixed using a …

In this paper, we study the aeroacoustic instability which occurs in a deep axisymmetric
cavity in a turbulent pipe flow. This phenomenon is the axisymmetric counterpart of the …

The coupling between fluid strain rate, local flame extinction, hydrodynamic instability, and
flame lift-off was studied in premixed swirl flames using multi-kHz repetition-rate OH …

In the recent literature, a growing number of research papers have been dedicated to
applying the techniques of global stability and sensitivity analysis to the design of flow …

The linear and nonlinear dynamics of two-phase swirling flows produced by the Grabowski–
Berger profile under the influence of a viscosity stratification are investigated. We perform …
