Application of the viscosity-expansion method to a rotating thin fluid disk bound by central gravity

Koichi Takahashi.

in Progress of Theoretical and Experimental Physics

July 2015; p ublished online July 2015 .

Journal Article. Subjects: Galaxies; Fluid Mechanics. 9639 words.

The 2D rotation of a thin fluid disk with a porous sink around the center is studied within the Navier–Stokes and Euler equations. The viscosity ([math])-expansion method is applied to the...

Clebsch Potentials in the Variational Principle for a Perfect Fluid

Hiroki Fukagawa and Youhei Fujitani.

in Progress of Theoretical Physics

September 2010; p ublished online September 2010 .

Journal Article. Subjects: Fluid Mechanics. 0 words.

Equations for a perfect fluid can be obtained by means of the variational principle both in the Lagrangian description and in the Eulerian one. It is known that we need additional fields...

Self-organization in foliated phase space: Construction of a scale hierarchy by adiabatic invariants of magnetized particles

Z. Yoshida and S. M. Mahajan.

in Progress of Theoretical and Experimental Physics

P ublished online July 2014 .

Journal Article. Subjects: Classical Mechanics; Fluid Mechanics; Plasma Physics. 7283 words.

Adiabatic invariants foliate phase space, and impart a macro-scale hierarchy by separating microscopic variables. On a macroscopic leaf, long-scale ordered structures are created while...
