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…
Role of wave scattering in instability-induced Langmuir circulation
S. S. Vergeles, I. A. Vointsev
We consider a classical problem about dynamic instability that leads to the Langmuir circulation. The problem statement assumes that there is initially a wind-driven shear flow and…
Alpha-effect in three-dimensional coherent vortex of conducting rotating liquid
Leon L. Ogorodnikov, Sergey S. Vergeles
We study one-point statistics of spiral turbulent pulsations on the background of three-dimensional large-scale vortex in a rotating fluid. Assuming that the helical flow is create…
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…
Velocity structure function in a geostrophic coherent vortex under strong rotation
Leon L. Ogorodnikov, Sergey S. Vergeles
We consider analytically pair structure function of turbulent pulsations on the background of a coherent geostrophic vortex in a fast rotating fluid. The statistics of the turbulen…
Velocity profiles of cyclones and anticyclones in a rotating turbulent flow
Vladimir M. Parfenyev, Ivan A. Vointsev, Alyona O. Skoba +1
Strong rotation makes an underlying turbulent flow quasi-two-dimensional that leads to the upscale energy transfer. Recent numerical simulations show that under certain conditions,…
