LLNL international collaboration on research in edge physics modeling

Principal Investigator: X. Q. Xu

Description

This work will develop and apply integrated edge modeling tools by leveraging the available resources at LLNL and with its international collaborators in China and Europe. We exploit LLNL FEP codes: BOUT, BOUT++, Corsica, UEDGE, TEMPEST and COGENT. The project will include verification and validation activities. The physics problems addressed will include formulation and simulation of RF heating/flow drive, edge transport and turbulence, GAMs, zonal flows, and ELMs. The simulation results will be validated against experiments in EAST, JET, KSTAR, HL-2A, and ITER design/operation scenarios.
