Potential flow Deluxe

The laminar, two-dimensional flow in HM 152 is a good approximation of the flow of ideal fluids: the potential flow. All physical systems described with the Laplace equation can be demonstrated with potential flow.

• demonstration of potential flow in a 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
• 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
• 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
