Hydraulics Library video demo

Watch 7 minute example on the water hammer effect!


For those of you new to the Hydraulics Library, we thought of giving you a brief feeling for its usage.

And for the Modelica connoisseurs out there, this is perhaps a reminder of the easy-to-build & easy-to-use Modelica & Dymola models supporting your systems development and optimization efforts. 

We selected for this demo a simple example: modeling and simulating the water-hammer effect

(Use the form below to access the video demo).

Water-hammer is the common term for the high and repetitive pressure peaks in a pipe filled with liquid, before a valve, when the valve is suddenly closed. The characteristic banging sound and vibrations give the name to the phenomenon.

Now, even if you are not a mechanical engineer, you have for sure experienced this at some time in your life. Remember the banging noise in the water line of your washing machine? Probably this is what happened!

And if you are an engineer, especially one in fluid applications design, you may be interested in this short demo, because it illustrates:

  • The Hydraulics Library components (from pipes, and tanks and valves to available complex applications)
  • How you build your system in Dymola, with drag-and-drop simplicity
  • How you set up the parameters
  • How you run, plot and interpret the results
  • How you change the design, to improve your systems performance.

Simply fill in your data below and watch this demo now.
