The 3D vortex particle method in parallel computations on many GPUs

• 3D Vortex-in-cell method was realized in parallel computation using many graphical cards (GPU).
• Leapfrogging and head-on collision of vortex rings phenomena are modelled.
• Numerical solutions were done for inviscid and viscous flow.
• Very good agreement with experimental pictures were obtained.

Parallel implementation of the Vortex-in-Cell (VIC) method for 3D flow on many graphics cards was presented. As test problems it was chosen the leapfrogging and head-on collision of two vortex rings for which a well documented visualization exists in the literature. Our aim was to show the great potential of the VIC method for solution of 3D flow problems and that it is very well suited for parallel computation.
