Rigidly rotationg perfect fluids

Astronomische Nachrichten, 1986
AbstractA class of stationary rigidly rotating perfect fluids in General Relativity is investigated. This class which is characterized by zero Simon tensor contains only the Wahlquist solution and its limits. It is shown how a recently given solution follows from the Wahlquist solution by a limiting procedure.

A crack in a perfect fluid

Moscow University Mechanics Bulletin, 2008
An analytic particular solution is obtained for a plane flow problem. The plane flow is forced in an incompressible perfect fluid by a rigid moving wall surrounding the fluid. The wall has the shape of an elliptic cylinder and rotates about its axis. It is found that, during the rotation of such a cylinder, there appears a “hanging” vortex sheet such ...

Revisiting perfect fluid dark matter: Observational constraints from our galaxy

open access: yesPhysics Letters, Section B: Nuclear, Elementary Particle and High-Energy Physics, 2016
We revisit certain features of an assumed spherically symmetric perfect fluid dark matter halo in the light of the observed data of our galaxy, the Milky Way (MW). The idea is to apply the Faber–Visser approach of combined observations of rotation curves
