Abstract

"Drifting cups on a meandering stream" is a same originating from the ancient China. It takes advantage of the stopover of the cup at the different positions on a meandering stream to choose a person sitting on the bank to participate the game. In this paper, a model is devised to make the cups move around or stop at some place on the stream as required by the game. A typical flow field Is abstracted and studied using the PIV technique and the topological analysis. Some motions of the cup on the stream have been explained in the mechanics theory.
