Potential Flow .

Flow Around Bodies                      

Specification Of Flow around Bodies

  • Demonstration of potential flow in a Hele-Shaw cell for visualising streamlines
  • Flow around supplied models: cylinder, square, rectangle, guide vane profile, various models for changes in cross-section
  • Modelling the flow around contours without models by overlaying parallel flow with sources or sinks
  • Water as flowing medium and ink as contrast medium
  • Hele-Shaw cell made of two glass plates arranged in parallel with narrow gap
  • Upper glass plate, hinged for swapping models
  • Bottom glass plate with cross-shaped water connections for generating sources/sinks, can be combined as required
  • Grid in the bottom glass panel for optimal observation of the streamlines
  • Flow velocity, water inlet and water outlet in sources/sinks as well as dosage of the contrast medium can be adjusted by using valves

Technical Data
