Analytical formulas for the velocity field induced by an infinitely thin vortex ring
Authors:Sam S. Yoon  Stephen D. Heister
Abstract:
Three different analytical solutions are presented for a potential vortex ring using three different streamfunctions. Verification studies confirm that all three approaches are valid. It is found that the solution obtained using the Biot–Savart law is the most efficient method due to its simplicity. It is shown that all analytical results are accurate to within machine accuracy and sample calculations are included. Copyright © 2004 John Wiley & Sons, Ltd.
