We explain the rotating polygon instability on a swirling fluid surface [GH Vatistas, J. Fluid
Mech. 217, 241 (1990) JFLSA7 0022-1120 and Jansson et al., Phys. Rev. Lett. 96, 174502 …

We present a study of polygons forming on the free surface of a water flow confined to a
stationary cylinder and driven by a rotating bottom plate as described by Jansson et …

We investigated the quasi-periodic oscillation (QPO) features in the accretion-powered X-ray
pulsar Cen X-3 observed by Insight-HXMT. For two observations in 2020 when Cen X-3 was …

The flow of two immiscible fluids completely filling an enclosed cylinder and driven by the
rotation of the bottom end wall is studied numerically. The simulations are in parameter …

We present an experimental study of 'polygons' forming on the free surface of a swirling
water flow in a partially filled cylindrical container. In our set-up, we rotate the bottom plate …

We study 'surface switching'quantitatively in flows driven by the constant rotation of the
endwall of an open cylindrical vessel reported by Suzuki, Iima & Hayase (Phys. Fluids, vol …

Flows in a cylindrical tank over a rotating bottom are investigated by laboratory experiments.
Despite the axisymmetry of the experimental setup, various anisotropic phenomena are …

Expanding our previous work on turbulent whirls [1] we have uncovered a similarity within
the similarity shared by intense vortices. Using the new information we compress the …

The origins of the words 'boundary','bound', and 'frontier'can be traced to two different
etymologies. The oldest comes from expressing the repetition of a loud noise, reverberated …

Rotating polygons are geometric patterns formed spontaneously by the free surface of a
rotating fluid driven by a rotating disk at the bottom of a partially filled cylindrical container …
