Exclusive: FCC prepares review of Disney’s TV licenses
Potential move could strip ABC of its ability to broadcast to stations across the country following Jimmy Kimmel’s “expectant widow” monologue comments.

Asylzahlen halbiert, AfD trotzdem stabil. Wer noch glaubt, die Partei lebe vom Migrationsthema, hat ihren Markenkern nicht verstanden: Sie mobilisiert Angst vor sozialem Abstieg, Unsicherheit, Wut aufs System. Lösungen? Fehlanzeige. Merz' „populistische Plagiate", stärken sie, statt sie zu schwächen. Wir brauchen endlich eine konstruktive Erzählung – keine Kopie von rechts gegen die Anti-Partei. #T

"Das ist ein Irrglaube": Darum bleibt die AfD stark
Die Asylzahlen sinken, doch die AfD bleibt stark. Das liegt auch an der allgemeinen Unzufriedenheit im Land. Denn die Partei punktet längst nicht mehr allein mit dem Thema Migration.

Ce soir c'est khorkhog.

Abstract: This work presents a numerical investigation of soot formation in the Cambridge lab-scale gas turbine combustor. Large-eddy simulations (LES) of a swirl-stabilized ethylene flame are performed using the flamelet generated manifold method coupled with a discrete sectional model to account for soot formation, growth, and oxidation. The study aims to elucidate the mechanism governing the spatial structure and intermittency of soot, supported by comparisons with experimental data. The predicted soot distribution agrees well with measurements, with peak concentrations near the bluff body. Flow recirculation is identified as the key mechanism driving soot accumulation in fuel-rich regions, where surface reactions dominate soot mass growth. Soot intermittency arises from fluctuations in the flow field driven by interactions between the flame front and the recirculation vortex. Two soot modeling approaches are evaluated, differing in their treatment of soot model quantities: the first approach employs on-the-fly computation of source terms (FGM-C), while the second uses fully pre-tabulated source terms (FGM-T). Their predictive performance and computational cost are compared in the context of unsteady, sooting flames in swirl-stabilized combustors.

Large eddy simulation of turbulent swirl-stabilized flames using the front propagation formulation: impact of the resolved flame thickness

Abstract: This work extends the front propagation formulation (FPF) combustion model to large eddy simulation (LES) of swirl-stabilized turbulent premixed flames and investigates the effects of resolved flame thickness on the predicted flame dynamics. The FPF method is designed to mitigate the spurious propagation of under-resolved flames while preserving the reaction characteristics of filtered flame fronts. In this study, the model is extended to account for non-adiabatic effects and is coupled with an improved sub-filter flame speed estimation that resolves the inconsistency arising from heat-release effects on local sub-filter turbulence. The performance of the extended FPF method is validated by LES of the TECFLAM swirl-stabilized burner, where the results agree well with experimental measurements. The simulations reveal that the stretching of vortical structures in the outer shear layer leads to the formation of trapped flame pockets, which are identified as the physical mechanism responsible for the secondary temperature peaks observed in the experiment. The prediction of this phenomenon is shown to be strongly dependent on the resolved flame thickness, when the filter size is used for modeling sub-filter flame wrinklings. Without proper modeling of the chemical steepening effects, the thickness of the resolved flame brush is over-predicted, causing the flame consumption rate to be under-estimated. Consequently, the flame brush detaches from the outer shear layer, resulting in a failure to capture the flame pockets and the associated secondary temperature peaks.
