Free and Forced Vortex

Free and Forced Vortex .

• The apparatus includes a clear acrylic cylinder on a plinth developed to produce & 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 caliper 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
