Dat shrug when you fkin own space in someone else's mind...i wouldn't want to go against me either 😱

I am sorry to keep milking this, but I am super proud of this publication and also super happy it made it as an editor's suggestion! @PhysRevFluids

Dear Twitterverse: does anyone have experience with multi-threading and/or distributed memory in #Julia @JuliaLanguage? We are seeing excellent performance on a single thread but poor perf in parallel. Tricks/tips welcome @gabrielweymouth @LorenaABarba @eigensteve @bernat_font

For the high roller, I am going to assume a CS/SE/math, and likely FAANG. So, $150k in SF is probably reasonable for a newly minted BS degree(s)? If the job is remote, then the salary is woah...

"Of the 431 Class of 2021 @RoseHulman graduates, 426 have been placed within six months of graduation, with an average starting salary of $73,800 and a high reported offer of $145,000. That’s a 99% placement rate." JFC, economically, i choose the entirely wrong path...

Our recent article in @JFluidMech explains different shear regimes in gravity flow of a granular material (why most of the recent models may fail except hybrid class models) @chemengiisc @iiscbangalore

How do large-scale structures develop in thermal convection? From this direct numerical simulation of Rayleigh-Bénard convection by Erwin van der Poel @poftwente @utwente one can see: Thermal plumes emerge and merge, building up the large-scale turbulent convection roll. #DNS

@gabrielweymouth @garethmckinley I'm a high-order finite-difference guy, so i'm probably out of my depth, but LBM [seems] like it can converge to some "DNS" results. https://t.co/zvXU44eAUA

This is very cool! You just know I am going to show this on opening day in my grad fluids class 2.25 this Fall! 🌊 ✈️ 🚀

@ToughSf In this simulation (not from my group, but from Venkat Raman's group at U. Michigan) you'll see a detonation propagate through layers of reactive mixture. https://t.co/3EQaoUjnuv

[Andrew Higgins @A_J_Higgins]

@ToughSf This work is quite theoretical, but detonations propagating into inhomogeneous mixtures is encountered in applications where there is not sufficient time for complete mixing of fuel and oxidizer, such as in rotating detonation engines (RDEs).

[Andrew Higgins @A_J_Higgins]

20 years ago, I started to work with my students on the problem of detonations propagating into inhomogeneous media. This new paper by Aslan Kasimov in @JFluidMech reveals a richer dynamics than we ever imagined:
