A coherent structure transport model for scrape-off layer turbulence
Zhichen Feng, James Myra, Junyi Cheng +5
Understanding the locality of high-temperature plasma energy deposition on material surfaces in fusion reactors is critical for design. Here, we utilize the Gyrokinetic ElectroMagn…
Triggers for plasma detachment bifurcation in the edge divertor region of tokamaks
Menglong Zhao, Thomas Rognlien, Ben Zhu +3
We report the discovery of the trigger for detachment bifurcation phenomenon in tokamak divertors, revealed through steady-state and time-dependent UEDGE simulations: The observed…
Physics insights from a large-scale 2D UEDGE simulation database for detachment control in KSTAR
Menglong Zhao, Xueqiao Xu, Ben Zhu +8
A large-scale database of two-dimensional UEDGE simulations has been developed to study detachment physics in KSTAR and to support surrogate models for control applications. Nearly…
Latent Space Mapping: Revolutionizing Predictive Models for Divertor Plasma Detachment Control
Ben Zhu, Menglong Zhao, Xue-Qiao Xu +4
The inherent complexity of boundary plasma, characterized by multi-scale and multi-physics challenges, has historically restricted high-fidelity simulations to scientific research…
