In industrial pipes, air laced with dust or droplets swirls like dancers in a waltz. But which math model to pick for the simulation? Tests show: the standard approach is more accurate than trendy new ones. This will speed up the design of dryers, filters, and sprayers.
An elastic drop falling onto a surface that repels water like a lotus leaf doesn't spread but stretches out a tail, like a pulled rubber band. Then the tail contracts, a bulb forms at the tip, and the entire drop bounces off. Inertia and gravity control the stretching, while elasticity keeps the liq
Scientists created a model that allows a quantum chip to simulate vortex flows. They rewrote fluid motion equations into rules for qubits and tested them on an eight-qubit superconducting processor. Virtual vortices behaved like real ones. Thus, quantum computers bring us closer to solving the ancie
New research shows that if you swirl water vigorously in a shallow dish, a vortex with an empty center forms. Waves on its surface, reflecting off the edges, accumulate energy — exactly like around a rotating black hole. This vortex became the first desktop model for a dangerous cosmic phenomenon —
Fluids that change thickness under pressure behave unexpectedly in porous materials. Scientists built a model that predicts their path, accounting for uneven pores and friction. This will change filtration, oil recovery, and our understanding of biological processes.
An experiment showed how a pair of vortices in liquid light play leapfrog. At high speed, a shock wave appears, the game breaks down, and the vortices vanish, releasing heat. This helps understand how motion decays in superfluid media.
Physicists have discovered that rain lifts plastic particles into the air, especially those that repel water. Upon impact, they get coated in water and turn into airborne beads that wind scatters across the planet. This changes our understanding of how plastic travels from the ocean into our lungs.
A new AI training method: first learn from 30,000 shapes, then fine-tune for the task. Just 450 examples reduce error to 0.36%. This speeds up the search for the best aerodynamic solutions.
A new study has, for the first time, self-consistently incorporated the recipe of double diffusion into an evolutionary code of planets and traced the fate of Jupiter and Saturn from the moment of formation. It turns out that even a thousandfold enhancement of mixing does not lead to significant sme
