“Drifting cups on a meandering stream” in Korea.

The Posuk-Chung Pavilion is a defunct irregular stone water channel in Kyongju, Korea, once used for the ‘meandering stream feast’ by kings of Silla Dynasty during the first millennium. The poets were seated around this stone water channel who composed the Chinese poems, overlooking the streams. They had to take the punishment drinks unless they finished the poem before the drifting cup filled with the rice wine arrived at their seats on the meandering stream. In this paper, we have made computer simulation as well as model experiment on the ancient meandering stream of the Posuk-Chung Pavilion. The computational results are compared with the experiment and the channel flow characteristics are delineated here. It is discussed how the present Posuk-Chung channel is morphologically distinguished from the Chinese and Japanese meandering streams. [ABSTRACT FROM AUTHOR]
