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.

Cumulus-Nielsen Fight Goes Dark as Bankruptcy Stay Takes Hold - Radio Ink
Cumulus's Chapter 11 bankruptcy has halted its landmark antitrust lawsuit against Nielsen. With a new board and new owners set to take over, the future of the case is anything but certain.

Imagine being so exhausted you can barely stand, yet thousands of people are waiting for you to give everything you have. Night after night. City after city.
There's a singer who knows this feeling intimately. After months of touring, she's running on empty—traveling by day, performing by night, adrenaline keeping her wired long after the final encore. Sleep won't come. The body is exhausted, but the mind won't stop. She captures this feeling in a song about desperate ti…

'Eingefrorene Bewegung' #FotoVorschlag 'Frozen Movement'
Ah I almost didn't want to post a photo for this topic until this photo came to my mind. And it's a frozen motion even literally... right?
More about this day:

The entire machinery of online discourse around building and creating has been so thoroughly captured by entrepreneurial "logic"
that we've lost the language to describe what it feels like to simply make a thing that helps someone,
give it away, and move on with your life.
I've been feeling this for a while now, and I suspect a lot of folks who have the itch to build feel it too, even if they haven't articulated it.

Omg, #immich just told me that we visited #rome 12 years ago. 12?! Omg - where does time go?
But I'm just - so - glad that I took those photos. And for this feature in Immich.
These reminders about our vacations and adventures.. Just so precious.
