HM 150.10 Visualisation of Streamlines Show data sheet (pdf file) Print page
Technical Description

  The laminar, two-dimensional flow in HM 150.10 is a good approximation of the flow of ideal fluids: the potential flow.
  HM 150.10 can be used to visualise streamline fields for flows around drag bodies and flow through changes in cross-section. The streamlines are displayed in colour by injecting a contrast medium (ink). Sources and sinks are generated via four water connections in the bottom glass plate. The streamlines can be clearly observed on 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 HM 150 base module. The water is supplied by HM 150. Alternatively, the experimental unit can be operated by the laboratory supply.
  The well-structured instructional material sets out the fundamentals and provides a step-by-step guide through the experiments.
