Flow visualization experiment was conducted for a cooling channel with Finger-stacked structure, which is proposed for the first wall cooling in a fusion molten salt blanket. In the experiment, the finger length and the gap width between the finger tips and channel wall were taken as parameters, and each flow field was discussed in detail.
