Template Potentials Technique with Fully- Parameterized Field Solver for High-current Beams Simulation*
نویسنده
چکیده
A three-dimensional (3D) particle-in-cell (PIC) code based on the template potential concept [1-6] has been upgraded by inclusion of a fully parameterized model for 3D space charge force calculations. The dynamics of a bunched 3D beam were studied for FODO channels having a conducting chamber with an arbitrary elliptical symmetry. The simulation results were in a good agreement with conventional 3D PIC models, but were obtained with ten to one hundred shorter computational times.

Mixed Large-Eddy Simulation Model for Turbulent Flows across Tube Bundles Using Parallel Coupled Multiblock NS Solver
In this study, turbulent flow around a tube bundle in non-orthogonal grid is simulated using the Large Eddy Simulation (LES) technique and parallelization of fully coupled Navier – Stokes (NS) equations. To model the small eddies, the Smagorinsky and a mixed model was used. This model represents the effect of dissipation and the grid-scale and subgrid-scale interactions. The fully coupled NS eq...
