Abstract-
This talk presents work on the 3D Vortex element method for incompressible flows. Particle redistribution schemes based on the face-centered cubic lattice are introduced. Flows around moving boundaries are considered. The terms due to the rotation or deformation of boundaries are included in the Biot-Savart summation. Near-wall vorticity is discretized with elements with specific shape functions. The flow around a spinning sphere at Re=300 and a spin rate WR/U = 0.5 is studied for three directions of rotation. Results for flapping and swimming motions are also presented.
