The equipment is a self contained unit
designed to study the mobile bed formation and two dimensional flow
observation The tank is made of stainless steel and consists of five
sections.
. Head tank with perforated plate to minimize turbulence and smoothen the flow.
. The working section containing sand is for study of the mobile bed
formation and to observe two dimensional flow patterns. Wire mesh is
provided to contain the sand. Plastics plates are used when two
dimensional flow is to be observed.
. The storage tank collects discharge from the working section and
acts as a reservoir. An adjustable overshot weir is provided to control
the water level in the working section. The tank also has a sand trap
to collect the over-spilled sand.
. A pump to draw water from the storage tank and deliver it to the
head tank. A water meter, and a flow control valve are also
supplied.
. An instrument carriage traveling on stainless steel tube rails
attached to the edges of the working section are designed such that the
carriage can travel length wise and crosswise over the working section. A
stainless steel vernier hook and point gauge is attached to the
carriage to measure the sand profile level.
The first three sections are joined together by flanges and the pump
unit is connected to the system by flexible hoses. Various models are
supplied to simulate different flow obstructions and diversions. An
aluminium dust or equal is supplied for two dimensional flow
observations.
TYPICAL EXPERIMENTS
- Sand bed formation under various flow rates.
- Erosion of sand bed around piers or branch canal.
- Two dimensional flow pattern around pier and branch canal.
