Flow Channels

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 enables flow visualization in conjunction with a reticule 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 aerofoil’s, which in conjunction with the inlet and discharge weirs, permit a varied range of open channel and flow visualization demonstrations.
