Abstract
Peristaltic flow generated in an asymmetrical two-dimensional channel with one fixed wall and one moving wall is investigated experimentally, in the range of large Reynolds number where peristaltic pumping has a possibility of engineering application. Visualized photograph of the stream line and the particle trajectory are shown, and the velocity profile in the flow is obtained by using the image processing. The experimental results are compared with the results of previous theoretical analyses. Comparison of them shows a good agreement and gives verification to the theoretical analyses. In the light of the experimental results, distinctive features of peristaltic flow at large Reynolds number is discussed.
