Effect of Additively Manufactured Wall Lattice Structures on Flashback Limits in a Hydrogen Jet Flame Combustor
Alexander Jaeschke, Thomas Ludwig Kaiser, Lukas Melzig +3
This study investigated how additively manufactured nozzles with body-centered cubic lattice structures reduce the flame flashback propensity in a hydrogen jet flame burner. Five d…
Linear stability and spectral modal decomposition of three-dimensional turbulent wake flow of a generic high-speed train
Xiao-Bai Li, Simon Demange, Guang Chen +4
This work investigates the spatio-temporal evolution of coherentstructures in the wake of a high-speed train. SPOD is used to extract energy spectra and empirical modes for both sy…
Modelling the response of a turbulent jet flame to acoustic forcing in a linearized framework using an active flame approach
Thomas Ludwig Kaiser, Gregoire Varillon, Wolfgang Polifke +4
This study performs a linear analysis of a turbulent reacting methane-air jet flame, with the goal of predicting the response of the reacting flow to upstream acoustic actuation. A…
Mean flow data assimilation based on physics-informed neural networks
Jakob G. R. von Saldern, Johann Moritz Reumschüssel, Thomas L. Kaiser +2
Physics-informed neural networks (PINNs) can be used to solve partial differential equations (PDEs) and identify hidden variables by incorporating the governing equations into neur…
From snapshots to manifolds - A tale of shear flows
Ehsan Farzamnik, Andrea Ianiro, Stefano Discetti +4
We propose a novel non-linear manifold learning from snapshot data and demonstrate its superiority over Proper Orthogonal Decomposition (POD) for shedding-dominated shear flows. Ke…
Global linear stability analysis of a flame anchored to a cylinder
Chuhan Wang, Lutz Lesshafft, Kilian Oberleithner
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 bee…
