This ESOLS Product of Fluid Mechanics related labs used to study both free and forced
vortices, and measure the vortex water surface profile. A vortex is a circular flow of a fluid
caused by sufficiently large velocity gradients. In practice, this can be observed when water
flows out of a basin into a pipe or when two fluids with different speeds meet each other.
The apparatus has a transparent tank with nozzles, various inserts on the water drain, an
impeller and a point gauge for detecting the vortex profiles. To form the free vortex, water is
introduced radially into the tank and flows through a ring to slow down. The vortex is created
by the flow out of the tank. There are four easily replaceable inserts of various diameters
available for the drain.
To form a forced vortex, the water is introduced tangentially. The vortex is generated via an
impeller driven by a water jet. The point gauges are used to measure the surface profiles of
the vortices. The speed of the vortex is also determined.
This unit can be operated by Laboratory supply of with any Hydraulic Bench.
