Model Hydraulic Studies of an Improved Turning Apparatus for Channels with Rapid Flow

Аннотация

An improved turning apparatus for channels with rapid flow is proposed. A description of a laboratory flume and model of the turning apparatus are presented. Graphical relations of the depths of the flow behind a bend in five transverse sections along four verticals are constructed as a result of hydraulic studies of the model of the turning apparatus. Results of investigations of the velocity structure of the flow in the apparatus are presented. Graphs of the variation of the relative velocities vav/v0 of the flow beyond the apparatus are constructed. The results of the investigations confirm the effectiveness of the improved turning apparatus for channels with rapid flow.
