Abstract :
Lithium (Li) flow experiment was conducted for a Li target of International Fusion Materials Irradiation Facility (IFMIF). In the experiment, Li plane jet of 10 mm in depth and 70 mm in width formed by a two contractions nozzle was tested in the velocity range of less than 15 m/s. In the present report, wave patterns (called as surface wakes) on the Li flow were measured by Pattern Projection Method. This is an image measurement of non-contact and three dimensions. The projected patterns, which were stripes in this study, were observed to be deformed according to the surface up-and-down. Three-dimensional surface shape could be obtained by analyzing the deformed patterns. By the method, surface wakes were successfully measured. The results were compared with a theoretical study and showed good agreement.
