A flow vessel with an elastic wall can deform significantly due to viscous fluid flow within it, even at vanishing Reynolds number (no fluid inertia). Deformation leads to an enhancement of throughput ...

This paper considers the steady two-dimensional radial flow of viscous fluid between plane walls which either converge or diverge. A general solution is obtained in terms of elliptic functions and the ...

Viscous streaming refers to the rectified, steady flows that emerge when a liquid oscillates around an immersed microfeature. Relevant to microfluidics, the resulting local, strong inertial effects ...

When a less viscous fluid moves in a more viscous fluid in porous media, the interface between the two fluids becomes unstable and deforms in a finger shape.

In viscous fluids, this measure, called “helicity,” fluctuates, and knots can transform or unravel. But scientists still don’t know when and why helicity dissipates.

"The most exciting achievement of our study was developing the first practical application of viscous electron flow, a concept previously seen as purely theoretical," said Bandurin.
