| Abstract: | Experiments on flow visualization of a 2-D traveling wave wall were conducted in a water tunnel and three kinds of methods,including H_2 bubble, particle tracking and DPIV, were used to visualize the flow field structure qualitatively and quantitatively. The results obtained in the experiments reveal the effects of parameter C/U on flow characteristic and provide a physical analysis of the fish-like swimming mechanism restraining the flow separation. Meanwhile, three methods of flow visualization are discussed in this paper. |
