The Navier-Stokes equation has been getting a lot of attention lately.

For those who want to take a closer look at what lies behind its different terms, here’s a short video by Lorelscience, in French, breaking down the forces at play.

V. Ocqueteau (University of Bordeaux) and his supervisor M. Tucsnak have a new publication in the Journal of Mathematical Fluid Mechanics:

They study the small vertical motion of a floating cylinder. Coupling the water wave equations with the body's equation of motion, they prove the well-posedness of the system by analyzing a Dirichlet-to-Neumann map.

I briefly wondered whether there might be a process of boundary layer separation happening too far forward in the water layer between wheel and rail, which would then be equivalent to "stall" on an aircraft wing, but on reflection I think what's going on here is a Couette flow, to which boundary layer separation is irrelevant. #fluidMechanics

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.

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.

#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).

Liquids are usually expected to flow continuously. But under strong extensional stress, viscosity alone can trigger sudden, fracture-like failure.

Could this help control flows in hydraulics, 3D printing, or even blood vessels?

When two cavitation bubbles of different sizes collapse, they form distinct jet patterns that affect local pressure and energy distribution.

Understanding these dynamics helps predict damage in hydraulic systems.

... 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...
