Features:

• Visualization of streamlines  
• Ink as a contrast medium  
• Various models included: drag bodies and changes in cross-section  
• Sources and sinks, individually or in combination  

The laminar, two-dimensional flow in Tesca Visualization of Streamlines is a good approximation of the flow of ideal fluids: the potential flow.  
32121 can be used to visualize streamline fields for flows around drag bodies and flow through changes in cross-section. The streamlines are displayed in color by injecting a contrast medium (ink). Sources and sinks are  generated via four water connections in the bottom plate. The streamlines can be clearly observed through the glass  plate during flow around and flow through.  
The water flow rate and the quantity of contrast medium injected can be adjusted by valves. The water connections  are also activated by valves and can be combined as required. Individual models can be cut out of a rubber plate  that is included.  

The experimental unit is positioned easily and securely on the work surface of the 32097 base module. The water is supplied by 32097. Alternatively, the experimental unit can be operated by the laboratory supply.
