1610 Flow on the Gel
Details
The purpose of this study is to verify the possibility of friction-drag reduction of a flow along a polymer substance. The velocity profiles of a flow along an inclined polymer wall were measured by a PTV method. These are compared with the exact solution of the thin flow driven by the gravity along an inclined wall. The velocity profile obtained the flow along the acrylic resin coincided with the exact solution, namely, parabolic profile. Small discrepancy between the profile of the flow along the polymer wall and the exact one was observed in this study. However, since it is too small, it is hard to determine whether there is a slip flow on polymer wall.
