Demonstration Capabilities:
Fixed, Smooth Bed Flow:
The flume may be used without sediment on the bed to demonstrate the following flow phenomena and governing equations:
Turbulence – flow visualization for example by dye injection from a hypodermic syringe (not supplied)
Flow measurement – using sharp crested weirs
Tranquil, sub-critical flow – movement of surface waves upstream against flow
Governing equations of open channel flow – Reynolds’ number, Froude number, continuity, Bernoulli’s equation, weir equations
Rapid, super-critical flow – dominance of inertial over gravity forces, ‘shock waves’ from flow obstructions
Hydraulic jump – transition from super to sub critical flow, air entrainment, mixing.
