modelParallelPumpDropOut
Cooling circuit with parallel branches and drop out of pump
Extends from Modelica.Icons.Example (Icon for runnable examples).
Information
6th test example: ParallelPumpDropOut
Same as 2nd test example, but with a drop out of the pump:The pump is running for 0.2 s, then shut down (using a ramp of 0.2 s) for 0.2 s, then started again (using a ramp of 0.2 s).
