[S04A-02] Generation of Secondary Flow and Capturing of Floating Garbage by using Skew Strip Roughness
Keywords:Secondary Flow, Skew Strip Roughness, Floating Garbage
In order to capture floating garbage, secondary flow generated by skew strip roughness on one side wall was used. The effects of interval length and skew angle on the strength of secondary flow were investigated and optimum arrangement was obtained. However, the lateral range of effective secondary flow was limited to a certain distance in this one-side arrangement of skew strip roughness. In the garbage capturing experiment, floats were transported to one side by secondary flow and high capture rate was established by using skew catching filter.
