Publikováno v: EAS Publications Series. 58:161-165

Presented is a brief review of firsthand laboratory experiments with the use of fast rotating shallow water for simulation of important 2D objects and phenomena of astrophysical fluid dynamics, which alternatively can only be studied theoretically, c

Autor: E.N. Snezhkin, K. B. Titishov, G. P. Chernikov, A. Yu. Rylov, Yu. M. Torgashin, A.M. Fridman

Publikováno v: Physics Letters A. 372:4822-4826

We report the first experimental observation of wave over-reflection from supersonic flows and over-reflection instability of such flows in laboratory simulations on differentially rotating free-surface shallow water. Characteristics of the instabili

Publikováno v: Physics Letters A. 349:198-211

A scheme of model experiments on differentially rotating free-surface shallow water is proposed for discovering and studying the over-reflection instability. The scheme allows suppressing two stronger instabilities possible in the simulations, i.e.,

Rotating shallow water modeling of planetary,astrophysical and plasma vortical structures (plasma transport across a magnetic field,model of the jupiter's GRS, prediction of existence of giant vortices in spiral galaxies)

Autor: G. P. Chernikov, K. B. Titishov, Mikhail V. Nezlin, E.N. Snezhkin, A. Yu. Rylov

Publikováno v: Discrete Dynamics in Nature and Society, Vol 3, Iss 4, Pp 251-266 (1999)

Three kinds of results have been described in this paper. Firstly, an experimental study of the Rossby vortex meridional drift on the rotating shallow water has been carried out. Owing to the stringent physical analogy between the Rossby vortices and

On the Hydrodynamical Conception of the Spiral Structure in Galaxies with a Velocity 'Kink' on the Rotation Curve (Theory, Laboratory Experiments, Numerical Simulation, Observations)

The hydrodynamical conception of the spiral structure generation in the galaxies with a “kink” on the rotation curve is discussed. It treats the spirals as density waves in gas component of galactic disks. The main results of the fifteen-year stu

Centrifugal instability in rotating shallow water and the problem of the spiral structure in galaxies

Autor: A. G. Morozov, E.N. Snezhkin, Aleksei M Fridman, M. V. Nezlin

Publikováno v: Physics Letters A. 109:228-231

A new instability predicte by theory to occur in rotating shallow water in which the rotation velocity has a discontinuity, in a regime where the flow velocity exceeds the characteristics velocity of the waves, has been found experimentally. The inst
