| Abstract Scope |
The divertor is a key component in tokamak-based nuclear fusion reactors to reduce plasma contamination and protect the walls by removing heat. Divertors are predicted to experience steady-state heat fluxes up to 20 MWm-2 and transients up to 1 GWm-2.
Here we investigate a range of additively manufactured (AM), high-surface-area, cellular lattices as candidates for divertor cooling structures using computational fluid dynamics simulations. While AM structures have been examined for fusion, research using lattices is minimal so there is great opportunity to innovate.
Thermal/hydraulic metrics, such as Nusselt number and friction factor, at low heat flux testing are used to indicate performance and predict the general properties for each lattice type. This allows for an appropriate selection of candidate lattice structures for future high heat flux testing. Initial results show increased cooling performance; with the potential for novel divertor cooling geometries which can only be achieved through AM lattices. |
