Specifications
 Demonstration of potential flow in a Hele-Shaw cell for visualizing streamlines
 Flow around supplied models: cylinder, square, rectangle, guide vane profile, various models for changes in cross-section
 Modeling 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
