FL 16.1 – Flow Visualisation

The flow visualization table allows to study the flow behaviour through different objects by flow lines, besides being able to simulate sources and sinks.

Description
Upstream, the ink is supplied through needles generating current lines. The ink flow is controlled by a regulating valve.
Handling the needle valves, we can introduce in the current sinks (points where water leaves the stream), sources (points where water enters the stream) or a combination of both.
Different models are supplied with the equipment: car profile, aerodynamic profile, circle, rectangle, square, teardrop, etc., with which we can clearly see the flow of current lines passing around these.
Learning Objectives
      • Study of the flow around different submerged bodies:
        • car profile
        • symmetrical aerodynamic profile
        • square
        • tear
        • triangle
        • semicircles
      • Ideal flow associated with sinks and sources
        • formation of Rankine half-body
        • formation of a circular Rankine oval
        • flow lines of a doublet
        • overlapping of sinks and sources.
    • Study of bi-dimensional flow through flow lines.
