[Ci.01] A Numerical Study of a Vortex Sheet Model for Vortex Rings

Keith Lindsay (Claremont Graduate School), Robert Krasny (University of Michigan)

A vortex sheet model is used to numerically study vortex ring dynamics. A Lagrangian numerical method and an adaptive tree-code is used to simulate the smoothed vortex sheet. Results are presented for azimuthal perturbations of an initially axisymmetric vortex ring and for the off-axis collision of two vortex rings.
