カエル皮膚表面上の流れ(生物の流れ(2),一般講演) Flow near surface on frog skin
A detail measurement of velocity gradient on wall surface is to better understand a friction drag against wall. We carried out the visualization of flow near the wall surface by confocal micro PIV system. In generally known, a surface of a living tissue has reduction of friction drag because of a tissue consisted of a hydro-gel. To know the effect of friction drag by surface materials, we developed the confocal micro PIV system for measurement of velocity gradient near the surface. It was found that the velocity profile of dropped flow on glass surface was similar to that of open channel flow. This system is suitable for measurement of friction drag effected on wall with free surface flow.
