Abstract
Recent progress about helical self-organization studies is reported.Extensive exploita5on of 3D nonlinear visco-resistive modeling, SpeCyl code, which describescurrent-driven dynamics typical of pinch configura5ons in cylindrical geometry.Magnetic topology studies are based on the Field Line Tracing code NEMATO and a newrefined tool to detect Lagrangian Coherent Structures is compared with results from atemperature equation solver.The following Physics Issues in helical self-organization are addressed:o Boundary Condi5ons and dimensionless parameters impact, (RFP, and circular Tokamak)o Formation of internal transport barriers, (RFP)o Temporary loss of opera5onal point, reconnec5on events, (RFP and circular Tokamak),o Alfvén waves excitation (RFP and circular Tokamak),RESULTS show:o Reasonable comparison (validation) with RFP experimental observa/ons,o Similarities between RFP and Tokamak-like configura/on.| File | Dimensione | Formato | |
