Motivated by the recent success in finding coherent structures in turbulent flows and
describing their noise emission using the Resolvent Analysis (RA), the method is applied to …

This study performs a linear mean field analysis of a turbulent reacting methane-air jet flame,
with the goal of predicting the response of the reacting flow to upstream acoustic actuation …

The precessing vortex core (PVC) phenomenon in swirling jets is a helical instability in the
flow driven by the coherent precession of the vortex breakdown bubble (VBB) around the …

a brief description of the linearized flow solver FELiCS and reviews six applications of the …

Precessing vortex core (PVC), a typical vortex structure, universally exists in swirling flow
fields and originates from the Kelvin–Helmholtz instability of the swirling shear layer. In the …

The precessing vortex core (PVC) is a self-excited flow oscillation state occurring in swirl
nozzles. This is caused by the presence of a marginally unstable hydrodynamic helical …

We study the impact of H 2 enrichment on the unsteady flow dynamics and thermoacoustic
instability in the prediction and control of instabilities in industrial turbines (PRECCINSTA) …

This article focuses on the effect of diverging angle of the pilot stage on swirl spray flame
dynamics near lean blowout conditions in a centrally staged lean premixed pre-vaporized …

In the field of gas-turbine engineering, entropy waves and fluctuations in fuel–air mixing are
of significant importance. The impact of either mechanism on thermoacoustic stability of the …

Swirled flows often feature global modes that become manifest as skew-symmetric helical
vortices, also known as precessing vortex cores, which dominate the flow dynamics. This …
