Abstract
A flow channel with finger-stacked structure (FSS) has been proposed for the first wall cooling in a molten salt blanket of a fusion reactor. To evaluate the feasibility of the FSS channel, it is necessary to simulate the condition of the fusion reactor; one-sided heating, rectangle channel, heating of heat transfer promotors, and strong magnetic field. One side heating and rectangle channel conditions were tested in previous studies. To evaluate the influence of the heating of the heat transfer promotor against the heat transfer performance, in this study the heat transfer experiment was conducted. In the experiment, Particle Reynolds number was ranged from 1500 to 5000, heat fluxes from the wall was from 0.03 to 0.07 MW/m2, and averaged heat flux of the finger surface was set at 10 %, 20%, 30 %, and 40 % of the wall heat flux. It was revealed that the heating of the finger did not influence against heat transfer performance.
