Evolution of critical buckling conditions in imperfect bilayer shells through residual swelling

Pedro Miguel Nunes Pereira de Almeida Reis, Matteo Pezzulla, Dong Yan, Anna Lee

We propose and investigate a minimal mechanism that makes use of differential swelling to modify the critical buckling conditions of elastic bilayer shells, as measured by the knockdown factor. Our shells contain an engineered defect at the north pole and ...

Cold pulse and rotation reversals with turbulence spreading and residual stress

Ning Yan

Transport modeling based on inclusion of turbulence spreading and residual stresses shows internal rotation reversals and polarity reversal of cold pulses, with a clear indication of nonlocal transport effects due to fast spreading in the turbulence intens ...

Advancing SOL simulations: avoiding the Boussinesq approximation and coupling closed and open magnetic flux surfaces

Paolo Ricci, Paola Paruta, Federico David Halpern, Fabio Riva, Christoph Wersal, Baptiste Jimmy Frei, Félix Benedito Clément Musil, Morgan Siffert, Jorge Ari Morales Mena

Plasma turbulence in the tokamak scrape-off layer (SOL) region, where magnetic field lines intersect the reactor inner walls, determines the heat load on the limiter or divertor targets. This is one of the most crucial issues on the way towards a fusion re ...

X-point Position Dependence of Edge Intrinsic Toroidal Rotation on TCV

Olivier Sauter, Basil Duval, Holger Reimerdes, Benoît Labit, Alexander Karpushov, Wouter Vijvers

Recent theoretical work predicts intrinsic toroidal rotation in the tokamak edge to depend strongly on the normalized major radial position of the X-point. With this motivation, we conducted a series of Ohmic L-mode shots on the Tokamak a Configuration Var ...

X-Point-Position-Dependent Intrinsic Toroidal Rotation in the Edge of TCV

Olivier Sauter, Basil Duval, Holger Reimerdes, Benoît Labit, Alexander Karpushov, Yann Camenen, Wouter Vijvers

Edge intrinsic rotation was investigated in Ohmic L-mode discharges on the Tokamak a Configuration Variable, scanning the major radial position of the X point, R-X. Edge rotation decreased linearly with increasing RX, vanishing or becoming countercurrent f ...
