HF 515A TILTING FLOW CHANNEL, 150 mm wide, Adjustable bed.

This is a self contained open channel designed for studying flow phenomena with change in bed slope. It is to be used with optional accessories and models below. The channel is of rectangular cross section supported by rectangular steel frame. Side walls are transparent to allow full observation and are supported by adjustable steel brackets to ensure accurate wall alignment.  Tilting can be adjusted by a manual screw jack. The middle section of the bed can be adjusted manually upward or downward by a screw. A head tank with a stilling baffle provides a smooth flow and water is returned to the storage tank via an end tank. Models are attached to the top edges or bed of the flume by screws. Screw holes at the bed can also be used for pressure tapping to measure pressure loss along the channel length.


The settlement of river water sediments over a long period of time results is a shallow river bed. Occasional dredging may be required to deepen the river bed for navigation purpose. The adjustable bed flow channel allows a study of flow under the simulated shallow and deepened river bed.
