Abstract
A liquid Flibe divertor is proposed as a fusion DEMO reactor divertor that can suppress the surface temperature with low velocity through turbulent promoters, which are necessary considering the low heat transfer performance of liquid Flibe. Using water as a simulant fluid, a pebble-sunk structure (PSS) is introduced herein as a turbulent promoter. The heat transport characteristic is evaluated by flow visualization and heat transport experiments. The experimental results show that the kinetic energy and the heat transport near the free surface are enhanced when the PSS is introduced.
