Variation of Stagnation Points Around a Circular Cylinder With Circulation
For the flow with complex velocity function
the stagnation points are the solutions to
where
is such that
is the circulation of the velocity about the cylinder.
If
the stagnation points are
and asvaries the stagnation points move around the cylinder. The streamlines and locations of the stagnation points for variousare shown below.
The equation of the streamlines is given by
