Numerical simulation of two-dimensional incompressible Navier-Stokes turbulence by Clebsch potentials
Shuntaro Murai, Naoki Sato, Zensho Yoshida
The Clebsch representation of a velocity field represents an effective tool for the analysis of physical properties of fluid flows. Indeed, a suitable choice of Clebsch potentials…
Partition of enstrophy between zonal and turbulent components
Hiroto Aibara, Zensho Yoshida
The partition of enstrophy between zonal (ordered) and wavy (turbulent) components of vorticity has been studied for the beta-plane model of two-dimensional barotropic flow. An ana…
Epi-two-dimensional fluid flow: a new topological paradigm for dimensionality
Z. Yoshida, P. J. Morrison
While a variety of fundamental differences are known to separate two-dimensional (2D) and three-dimensional (3D) fluid flows, it is not well understood how they are related. Conven…
Generalized Beltrami flow -- a model of thin-disk and narrow-jet system
Z. Yoshida, N. L. Shatashvili
In the vicinity of a massive object of various scales (ranging from young stars to galactic nuclei), mass flow creates a spectacular structure combining a thin disk and collimated…
