I did a weird thing this morning. I was giving the dogs water from a hose out back. turned on the hose and used my thumb to spread the water around... all of a sudden the flow kind of sucked onto my thumb and some sort of venturi effect gave my thumb a barotrauma. It literally feels like I got my thumb stuck in a vacuum hose or something. Damn thing has been low level aching all day.

CW: Motiviation story-telling video about scientific research in fluids
I don't think I have ever seen #FluidMechanics research look so cool.

Beyond excited.. this is on at the #RoxyCinema
I’m pretty sure Ive only ever watched it on VHS or YT. It has it all.. #submarines #coldwar #practicaleffects and for once low Reynolds number #fluidmechanics is appropriate. 🤪
When i give general talks on the oceans to public audiences i often use a movie as a familiar prop to ease people in at the same time as giving their preconceptions a nudge 😎.. ive used this one a few times. It provides excellent service.

Today we’re sharing a slightly different piece of our reading list, stepping away, just for a moment, from the Leidenfrost effect to explore… the #physics of footballs ⚽
At every World Cup, the official ball is completely redesigned under strict physical constraints. Far from being a simple design object, it becomes a real-world laboratory for #FluidMechanics.

#FluidMechanics #FluidDynamics #AskFedi #DuckDuckFedi hey, I'm wondering which is better for cooling ? The desk isn't a perfect seal if you're wondering, air can vent, but slowly.
This computer is in a pull-push configuration, the GPU at the back is pulling fresh air in and the radiator is pushing hot air out as drawn by arrows. The radiator "pushing" fans are stronger than the GPU's "pulling" fans, so there is negative pressure, which means some air gets sucked in from surrounding case intakes (above, below etc).

Magnetic fields can dramatically reorganize fluid motion.
Using coupled fluid–thermal–structural simulations, this work shows how MHD effects suppress jets and vortices while altering heat transfer, mass transport and wall stresses.

Why can some fluids harden under impact?
Researchers tracked millimeter-sized cornstarch droplets hitting a surface and uncovered three distinct impact regimes, including a surprising liquid-to-solid transition during spreading.

From smooth liquid sheets to chaotic crowns, increasing impact speed transforms droplet splashing.
This work links that transition to Reynolds number and uncovers how instabilities shape droplet size and velocity.

Predicting droplet-fiber interactions is now more accurate: a validated semi-empirical model captures the maximum droplet volume across a wide range of fiber sizes and wettabilities.

🍔👌 How do you hold a #hamburger? If you're like most of us, you're doing it wrong! A team of researchers in #Japan used #3D modeling and #engineering to find the most efficient grip to keep your toppings from sliding out.

... However, I quite often cook fried eggs, and it occurs to me that the "old saw" explains why it's so difficult to fish stray little bits of eggshell out of the pan, and its formal meaninglessness explains why it's not entirely impossible. #fluidMechanics
-
Been musing on the old saw that objects in a Stokes flow can never collide. Came to the conclusion that it's formally meaningless, because when the objects get close to colliding, the streamwise spatial derivative of the velocity becomes large compared with the transverse spatial derivative of the velocity, so that inertial forces dominate over viscous forces and it's not a Stokes flow any more...

Flow net (Hydrology 💧)
A flow net is a graphical representation of two-dimensional steady-state groundwater flow through aquifers. Construction of a flow net is often used for solving groundwater flow problems where the geometry makes analytical solutions impractical. The method is often used in civil engineering, hydrogeology or soil mechanics as a first check for problems of flow under hydrau...

David Popovici’s 46.51s in the Men’s 100 Free at #AQUASingapore25 (2nd fastest ever... amid questions over the WR holder's consistency) defied velocity decay across the closing 50m with textbook stroke-length efficiency: Physics doctoral thesis in #FluidMechanics defended! 😉

You’d think I learn - accidentally found myself in a decent physical bookshop. Among the haul is this lovely work. “Clouds” - a perfect for me mix of #fluidmechanics and #art… illustrations are line drawings or art works… you know the sort - Turner, van Gogh, Ruskin etc. plus heaps new to me - #clouds - now.. to find time to read it properly instead of doomscrolling. 😐 #UnityBookshop

flying north from Ōtautahi yesterday afternoon and this had all the #FluidMechanics - waves, sunglint on braided rivers, clouds, and best of all lift keeping us in the air. Unfortunately the latter was a little conditional as we had some engineering issues that sent us back to CHC and so my dreams of a nice friday afternoon cuppa at home evolved into two more flights to get home about 1030pm and not in the mood for a cuppa. #FirstWorldProblems

it is kind of wild to learn that #FluidMechanics played an integral role in the creation of #CUDA and in turn ushering in an era of #GPGPU and #AI
