Thanks to hard work of -among others- T. Menard and E. Reyes, I've been involved into this research using the Archer3D code to study particle capture. Out now: ar.copernicus.org/articles/4/2...
Numerical study of the collection of aerosol particles by falling deformable drops
Abstract. The free fall of a drop through gas loaded with solid particles gives rise to multiple physical interactions, which remain poorly documented, especially when the drop is no longer spherical....

It's single-phase Tuesday again! (First one, actually). Here's some grid turbulence loosely inspired by the paper of Usama et al. (doi.org/10.1016/j.co...) calculated in Basilisk (basilisk.fr). You see volume magnitude iso-surfaces with structure shedding. Visu in Paraview.

@esa.int isnn't marketing itself enough. All the world praises only NASA for the Artemis mission, even though the European Service Module (which is like half of the ship, good luck flying w/o it) is visible in almost all mission shots... (that circular thing to the left of the Moon here). Humanity.

As I'm sure nobody has any idea about: 15y ago I have designed the cover of the ERCOFTAC (#ERCOFTAC) bulletin. (The graphic, seen below, has the color-manipulated foaming waters of the Polish Oder river.) As I have just been asked to redesign it, here's a goodbye look. New one premieres soon!

On an unrelated note, here's water coating a perforated solid at Re=46. There's a high-Re air coflow too, eventually a film is established though. Such processes take place e.g. in cooling towers's heat exchangers. Fresh out of the oven, simulated in Basilisk.

Today, I replaced a leaky/cracked adapter in the hot water outlet of a 300l boiler. I wonder what motivated whomever had previously decided to install this part made of... plastic. (Makes for a great non-AMD Threadripper, if you catch my drift). Darn, AI ain't replacing no plumbers I tell you.

Is that a Petri Dish? No, it's viscous liquid in an (unnecessarily violent) rotational flow inside a solid cylinder. Color is vorticity. Simulation in Basilisk (www.basilisk.fr and bview).

BTW, fixed a car radio. Off the bat I hear some rattling in it, and inside I discover ...4 euro coins (see? fixing stuff *does* pay off!), turns out prev owner's kids used the CD slit "as a vending machine"... A coin stuck in the CD changer's magnet, others were randomly shorting the circuit. Nice.

Made this cabinet, on and off over the last 7 mo. As usual, *all* wood is palette/garbage/dumpster_finds. So its cost was 0 (but the man-hours would take you back some 4k€ easily). Some tech infos in the image alt-texts. Had tons of fun - and that's why it was made. #DIY #woodworking

Mainstream media takes stories like: dx.doi.org/10.1139/apnm-2023-0594, and runs FAR with them ("meat is good for you!"). Risky. A talented statistician can use NHANES data even to prove the existence of Atlantis. Oh, and the work is sponsored by National Cattlemen’s Beef Association. No kidding!

Witnessed a skirmish with an anti-nuclear activist about what the lack of river/sea water means for a plant (coal vs nuclear). He says: "obviously, the coal plants do NOT use water for anything, while the nuclear do". Humanity is lost

The 1926 silent movie "The Johnstown Flood" showcased hundreds of early proofs of why fluid mechanics breaks your SFX. E.g. in this composite (~100y ago!) shot,we see a miniature flood,matchsticks pretending to be tree logs, people (rotoscoped in) and ...droplets with d=15cm. Good luck with that!
