This chapter derives the velocity fields and properties for some analytical flows involving a spread distribution of vorticity. Different examples of axisymmetric vorticity patches are presented, e.g. the rigid-body vortex patch and the inviscid vortex patch. They are convenient analytical solutions to study and validate numerical vortex methods. The inviscid vortex patch is studied in details in this chapter since it is highly used in Part VII to investigate the different aspects of vortex methods. The velocity field of a rectangular vorticity patch (or 2D vortex brick) is also provided.
