AYJM36 The Vortex Instrume Fluid Mechanics Experiment Equipment Teaching Equipment

Transparent vessel – users can see the”vortices from all angles • Includes

atraverse probe to measure water surface profile • Low-voltage variable speed

motor”for safety

The apparatus comprises a clear acrylic cylinder on a plinth designed to produce and measure free and forced vortices. The free vortex is generated by water discharging through an interchangeable orifice in the base of the cylinder, and the resulting profile is measured using a combined calliper and depth scale. The forced vortex is induced by a paddle in the base of the cylinder, which is rotated by jets of water. The profile of the forced vortex is determined using a series of depth gauges.

Velocity at any point in the free or forced vortices may be measured using the appropriate pitot tube supplied. Dye crystals (not supplied) may be used to demonstrate secondary flow at the base of the free vortex.
