The swirl number is defined as the radius-weighted ratio of axial flux of angular momentum to the axial flux of axial momentum.

SWIRL_NUMBER = FLOWRATE(radius*tangential-velocity) / FLOWRATE(radius*axial-velocity)

You can use custom field functions to obtain radius*tangential-velocity and radius*axial-velocity. Some users use a reference radius in the denominator such that: Denominator = radius_ref*FLOWRATE(axial-velocity)
