Kinetic energy of clouds is gained by mass inflow and dissipated in cloud collisions. The collisions give rise to a viscosity in a spatially averaged gas dynamical picture, which connects them to angular momentum transport and mass inflow. It is found that CND and torus share the same gas physics in our description, where the mass ","authors_text":"2), 2) ((1) CDS, (2) MPI fuer Radioastronomie, (3) ITA, Bonn, B.
