DOI: 10.1007/s00332-017-9424-z
Abstract: We prove that any weak space-time $$L^2$$L2 vanishing viscosity limit of a sequence of strong solutions of Navier–Stokes equations in a bounded domain of $${\mathbb R}^2$$R2 satisfies the Euler equation if the solutions’ local enstrophies… read more here.

DOI: 10.1016/j.colsurfa.2019.124271
Abstract: Abstract In this study a stretching of a viscous liquid bridge formed between two flat solid parallel substrates is investigated experimentally. The stretching of the liquid bridge is caused by the constant acceleration of one… read more here.

DOI: 10.1017/jfm.2017.327
Abstract: Rotating flow in which the angular velocity decreases outward while the angular momentum increases is known as ‘quasi-Keplerian’. Despite the general tendency of shear flow to break down into turbulence, this type of flow seems… read more here.
