On the influence of a large scale coherent vortex on the turbulent cascade
large scale coherent vortex turbulent cascade
2009/11/16
We investigate the flow between coaxial rotating disks in the situation where a strong axial vortex is present over a turbulent background. This is nonstationary and inhomogeneous as is common in most...
This paper applies the Hamiltonian Approach (HA) to two-dimensional motions of incompressible fluid in curvi-linear coordinates, in particular on a sphere. The HA has been used to formulate governing ...
Some estimates on the space scales of vortex pairs emitted from river mouths
space scales vortex pairs river mouths
2009/11/12
Two-dimensional vortex pairs are frequently observed in geophysical conditions, for example, in a shelf zone of the ocean near river mouths. The main aims of the work are to estimate the space scales ...
Methods to describe barotropic vortices by global fields and vortex characteristics
barotropic vortices global fields vortex characteristics
2009/11/12
Results from an experimental study of vortices in a rotating shear layer are presented. The data are in the form of maps of the instantaneous horizontal velocity field obtained by a particle tracking ...
Model for vortex turbulence with discontinuities in the solar wind
vortex turbulence discontinuities in the solar wind
2009/11/12
A model of vortex with embedded discontinuities in plasma flow is developed in the framework of ideal MHD in a low b plasma. Vortex structures are considered as a result of 2-D evolution of nonlinear ...
Numerical simulation of helical-vortex effects in Rayleigh-Bénard convection
Numerical simulation helical-vortex effects Rayleigh-Bénard convection
2009/11/9
A numerical approach is substantiated for searching for the large-scale alpha-like instability in thermoconvective turbulence. The main idea of the search strategy is the application of a forcing func...
Model of strong stationary vortex turbulence in space plasmas
Model strong stationary vortex turbulence space plasmas
2009/10/30
This paper investigates the macroscopic consequences of nonlinear solitary vortex structures in magnetized space plasmas by developing theoretical model of plasma turbulence. Strongly localized vortex...
