概要

Efficient heat transport and energy conversion are key factors for realizing a commercial
fusion reactor. A promising method for enhancing heat transport performance and simplifying the transport
system is thermosiphon. However, the maximum heat flux in the evaporation unit [namely, boiling heat
transfer (BHT)] of the thermosiphon system should be improved to remove heat at high heat fluxes
(>10 MW/m2). To improve BHT, we propose a new technique using a vibration material excited by boiling
bubbles. In this study, we investigated the characteristics of BHT with and without the vibration material
with pure water at atmospheric pressure to demonstrate our concept. We demonstrated that the vibration
material enhances BHT when the vibration is synchronized with the frequency of boiling bubbles emitted
from the heating surface.
