Fig. 5
Polar components of a the velocity field of a vortex. Top: radial velocity. Bottom: azimuthal velocity, where the axisymmetric part ⟨vφ⟩ is carried out. The pressure maximum is indicated by a black cross. The snapshot is taken at t = 200 orbital periods. The dotted line in the bottom panel indicates fluid in exact Keplerian rotation.
