A droplet’s shape can determine where it travels.

As a buoyant droplet deforms in a microchannel, the resulting hydrodynamic lift can oppose buoyancy and move it toward the channel center. Larger droplets experience stronger centering forces.

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.

What should a publication in fluid mechanics contribute to?

Physics of Fluids is evolving its positioning around a simple principle: “Physics First”, placing the advancement of knowledge in physics at the heart of its editorial policy. An interesting shift to follow for the scientific community.

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.

Can surface geometry be used to actively shape heat-transfer flows?

Corrugated Diamond TPMS structures show how small changes in a periodic surface can generate mixing, separation and reattachment, with measurable gains in convective heat transfer.

In complex flows, finding a correlation is often only the beginning.

Causal analysis asks a harder question: which physical variable influences another, and in which direction? This review explores how data-driven methods can address that challenge.

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

Sometimes improving water use isn't about storing more water, but about controlling where each raindrop goes.

A biodegradable spray creates hydrophobic soil ridges that redirect rainfall toward crop seeds, reducing losses to evaporation while using surface wettability as a design tool.

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.

Why does viscosity matter for liquid levitation?

High-speed imaging reveals that more viscous liquids need larger oscillation amplitudes to stay levitated, while the upper and lower interfaces respond very differently to dissipation.

Bubble rupture is not a single process but a sequence: hole opening, rim retraction, and jet focusing.

Surface tension accelerates all stages, while viscosity mainly determines whether the final jet survives or collapses.
