Abstract:

A new method for the numerical simulation of three-dimensional incompressible flows is described. Our vortex-in-cell VIC method traces the motion of the vortex filaments in the velocity field these filaments create on an Eulerian mesh via the fast integration of a Poisson equation. By incorporating the viscous or subgrid-scale effects into a filtering procedure, the computed scales of motion are assumed to be essentially inviscid. Results on tracing a periodic array of single vortex rings are compared with a Greens function calculation. Author
