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…
Detachment control in KSTAR with Tungsten divertor
Anchal Gupta, David Eldon, Eunnam Bang +7
KSTAR has recently undergone an upgrade to use a new Tungsten divertor to run experiments in ITER-relevant scenarios. Even with a high melting point of Tungsten, it is important to…
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…
Theoretical and Global Simulation Analysis of Collisional Microtearing
Kaixuan Fan, Xue-Qiao Xu, Ben Zhu +3
This study delves into Microtearing Modes (MTMs) in tokamak plasmas, employing advanced simulations within the BOUT++ framework. The research, centering on collisional MTMs influen…
