Abstract: The purpose of this study is to investigate the characteristics of
the flow through the Jonangu channel which is used for ceremonial game called
as 'Kyokusui-no-En' in Japanese. The geometry of the
channel is measured, a visualization technique is used to measure the actual
flow characteristics, and then a numerical flow model is used to represent the
flow including unsteady flow characteristics. Numerical model of drifting cup
is introduced to investigate an interaction between flow and motion of the cup.
Finally, the intention of the channel design is interpreted from the viewpoint
of fluid mechanics using observed and calculated results.
