Maintenance of a columnar vortex by inertial waves in rotational turbulence
Nikolay A. Ivchenko, Sergey S. Vergeles, Daniil D. Tumachev +1
We develop a theory that determines the radial profile of the mean velocity in a coherent geostrophic vortex forming in a turbulent rapidly rotating fluid. Following the conditions…

Absorption and reflection of inertial waves by a geostrophic vortex
Nikolay A. Ivchenko, Sergey S. Vergeles
We study interaction of inertial waves with geostrophic flow in a rapidly rotating fluid system. In accordance with experimental conditions in [1, 2], we consider inertial waves, w…

Mixing in two-dimensional shear flow with smooth fluctuations
Nikolay A. Ivchenko, Vladimir V. Lebedev, Sergey S. Vergeles
Chaotic variations in flow speed up mixing of scalar fields via intensified stirring. This paper addresses the statistical properties of a passive scalar field mixing in a regular…
