Model Studies of Chlorine Solution Dispersion in Turbulent Pipe Flow.

Research output: Book/ReportOther report


First, a detailed study was made of a small full-scale nozzle in a water tunnel (Nozzle Model) in order to determine the nozzle characteristics from both the hydraulic and vibration viewpoint. Second, the overall dispersion pattern downstream from the injection point was studied in a pipeline; this was called "Dispersion Model." Nozzle Model: An overall view of this model in operation is shown in Photo 1. Water, marked with potassium permanganate, is being injected through the nozzle. The purpose of this model was to make as nearly full .. sale tests as possible of the injection nozzle. The tunnel used is 13 in. high and 12 in. wide throughout the test section and permitted velocities up to about 16 fps. The stream, before entering the test section, is contracted at the top in such a way that the velocity is higher at the top of the test section than at the bottom. Thus, the flow in the tunnel represents the portion of the velocity profile near the wall of a larger pipe. The graph in Fig. 1 shows a comparison of the measured profiles in the tunnel with oa1culated turbulent profiles for several representative pipes.
