Abstract
We study the event-by-event generation of flow vorticity in the BNL Relativistic Heavy Ion Collider collisions and CERN Large Hadron Collider collisions by using the hijing model. Different definitions of the vorticity field and velocity field are considered. A variety of properties of the vorticity are explored, including the impact parameter dependence, the collision energy dependence, the spatial distribution, the event-by-event fluctuation of the magnitude and azimuthal direction, and the time evolution. In addition, the spatial distribution of the flow helicity is also studied.
