Heated Discharge from Flume into Tank

Information obtained in laboratory experiments is given on the physical processes producing temperature and velocity distributions when heated water is discharged from a channel into a wide, deep impoundment. Both the outlet channel and the receiving tank in the experiments had rectangular cross-sections, but the tank was more than 10 times wider and deeper than the channel. The tethered-sphere method was developed to measure local velocities; local temperatures were also measured and surface spreading patterns were recorded photographically. Investigated densimetric Froude numbers and Reynolds numbers at the outlet ranged from 0.6 to 7.2 and from 1,500 to 9,600, respectively.
