Hello—this is Ken Burns, reaching out on behalf of Alex Vindman for Senate.
I have dedicated my life to sharing America’s stories through films. They examine crucial moments in our nation’s history and the threats to our democracy. These stories are not easy.
Today, our country is facing its own reckoning, and the stakes have never been higher. That is why I am reaching out.
Alex Vindman––who I first met in 1983 while filming my documentary, the Statue of Liberty, when he w…

"A guest-singer from Spain, for the producer's previous project Nakatomi, kept repeatedly singing "venga" in their songs, which means "come" in Spanish. This led to the name 'Vengaboys' as their following project. So yes, Vengaboys actually means "Comeboys".

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.

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.

State Representative James Talarico, and his recent interview on The Late Show with Stephen Colbert:
CBS said it did not block the interview from airing, but provided legal guidance that broadcasting it could trigger the Federal Communications Commission’s equal-time rule.
Colbert’s show instead posted the interview on YouTube.
When CBS Austin asked about Talarico announcing he's raised $2.5 million in the 24 hours following the interview, Jasmine Crockett said,
