- 論文の詳細を見る
When a viscoelastic fluid flows out from a horizontally placed rectangular duct, many cracks and protruding ridges are formed on the upper surface of the jet. This anomalous phenomenon is reported for the first time by the authors. We investigate the critical point of this anomalous phenomenon under various conditions .Fourteen ducts having various heights, widths and lengths are used in this study. They have knife-edge-shaped or semicylinder-shaped duct exits. We also use four kinds of fluids having different flow properties. Moreover, we find an empirical formula for the critical point of the anomalous phenomenon through use of the dimensional analysis method.
