| Project Detail |
As fusion machines move toward a burning-plasma regime, liquid first walls and blankets may be needed to handle first-wall heat-flux, reduce erosion, and eventually to convert energy and generate tritium fuel. Repetitively pulsed fusion designs may require extreme electrode survivability, where the electrode may be solid, liquid, or a combination of both. It is critical to address how plasma dynamics in the fusion plasma will couple with both liquid-metal and electrode-material dynamics for fusion energy to become realizable. This Capability Team will use fluid and reduced kinetics, including building on its existing open-source simulation technology, Gkeyll, and a multi-phase, incompressible magnetohydrodynamic model, to study liquid- and solid-wall dynamics in the presence of fusion plasma and to experimentally validate aspects of the modeling tools. The team will perform high-fidelity kinetic plasma simulations that can account for complex plasma-wall interactions to support the development of multiple lower-cost fusion concepts.
