Flow around Bends in Stable Channels

Abstract
The purpose of the project discussed herein was to make careful flow measurements under laboratory conditions, to record, and to study the phenomenon of flow around a stable curved channel. An open channel, 18 in. wide and 10 in. deep, was built of transparent pyralin sections so they could be fitted together in combinations of tangents and curves. Motion pictures were taken of the flow phenomena as indicated by objects floated on the water surface, dragged or rolled on the stream bed, or held in suspension. The latter was accomplished by use of drops of a mixture of n. Butyl Plithalate and technical Xylol, colored with a deep red oil dye and having the same specific gravity as that of water.
