Welcome to the SciDAC-4 PARTNERSHIP Center for
High-Fidelity Boundary Plasma Simulation (HBPS)
(Headed by Choong-Seock Chang, PPPL)
The HBPS SciDAC Partnership Center will develop advanced fusion simulation codes based upon first-principles-based physics models to provide insight into edge plasma physics in magnetic fusion devices. Collaborations with the SciDAC Institutes, and with ECP Co-Design and Software Projects, will ensure reliable and efficient solution of validated models on extreme-scale, high-performance computers.
This figure shows an electrostatic potential perturbation from a petascale simulation of full-function gyrokinetic ion temperature gradient turbulence in realistic global DIII-D geometry. The magnetic separatrix surface is highlighted in the edge region.
The movie shows electrostatic turbulence across the separatrix at the outside midplane. Shearing of the pedestal turbulence eddies by a sheared poloidal flow and formation of blobby turbulence can be seen. (Watch in HD for best results)
This movie explains the physics of the self-generated bootstrap current in the narrow H-mode edge pedestal in tokamak plasmas, and emphasizes the role of trapped particles (published in Physics of Plasmas, 2016).
