Abstract
The present study involves a novel computational technique, regarding simultaneous use of the pseudo particle method, Poisson integral method and a special-purpose computer originally designed for molecular dynamics simulations (MDGRAPE-3). In the present calculations, the dynamics of two colliding vortex rings have been studied using the vortex method. The present acceleration technique allows the calculation of 107 vortex elements. The reconnection of the vortex rings was clearly observed, and the discretization error was nearly negligible.
