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.
Study of the flow around different submerged bodies:
symmetrical aerodynamic profile
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.
