Forced Vortex Flow

  • Forced vortex flow is one in which the fluid mass is made to rotate by means of some external agency. The external agency is generally the mechanical power which imparts a constant torque on the fluid mass. Then, in such a flow there is always expenditure of energy. The forced vortex motion is also called flywheel vortex or rotational vortex.

Example

  • Rotation of water through the runner of a turbine;
  • Rotation of liquid inside the impeller of a centrifugal pump.
  • Rotation of liquid in a vertical cylinder.

Free Vortex Flow

  • Free vortex flow is one in which the fluid mass rotates without any external agency. The whole fluid mass rotates cither due to fluid pressure itself or the gravity or due to rotation previously imparted. The free vortex motion is also called potential vortex or ir-rotational vortex.

Example

  • Flow around the circular bend.
  • A Whirlpool in a river.
  • Flow of liquid in centrifugal pump casing after it has left the impeller.
  • Flow of water in a turbine casing before it enters guide vanes.
