CFD evaluation and optimization of the HEMJ divertor cooling design

摘要

As part of the EU-DEMO prospective design studies, a He-cooled divertor concept has been developed by Karlsruhe Institute of Technologies (KIT). Using multi-jet cooling, the aim is to provide a robust solution that is capable of coping with heat fluxes as high as 10 MW/m(2) under stationary loading conditions. Using the CFD simulations the cooling performance was evaluated and a configuration providing the lowest pipe temperature was identified.
