Flow Channel.
Flow Channel
The channel consists of a clear acrylic working section of large
depth to width ratio incorporating undershot and overshot weirs at the
inlet and discharge ends respectively. Water is fed to the streamlined
channel entry via a stilling tank to reduce turbulence. Water
discharging from the channel is collected in the volumetric tank of the
Hydraulics Bench and returned to the sump for recirculation. A dye
injection system incorporated at the inlet to the channel permits flow
visualization in conjunction with a graticule on the rear face of the
channel. Models supplied with the channel include broad and sharp
crested weirs, large and small diameter cylinders and symmetrical and
asymmetrical aerofoils which, in conjunction with the inlet and
discharge weirs, permit a varied range of open channel and flow
visualization demonstrations.
