Physics-informed neural networks (PINNs) can be used to solve partial differential equations
(PDEs) and identify hidden variables by incorporating the governing equations into neural …

The transient dynamics of the precessing vortex core (PVC), a globally unstable mode, in an
intermittently shape-transitioning swirl flame is investigated by means of simultaneous OH …

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 response to forcing of a 2D laminar premixed slot flame is investigated by means of
linear analysis, based on the compressible flow equations with a two-step reaction scheme …

This study investigates the linear stability of a laminar premixed flame, anchored on a
square cylinder and confined inside a channel. Many modern linear analysis concepts have …

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

The main focus of this paper is to discover the link between flame macrostructure and
thermoacoustic instability in a centrally staged swirl burner. In practical combustors, the flow …

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 …

The dynamics of an axisymmetrical swirling jet is studied via global linear stability and
resolvent analyses. The modeled flow represents a combustor-like swirling jet, that is …

This work investigates the spatio-temporal evolution of coherentstructures in the wake of a
generic high-speed train. Spectral properorthogonal decomposition is used to extract energy …
