Information
This information is part of the Modelica Standard Library maintained by the Modelica Association.
4th test example: PumpAndValve
The pump is running with half speed for 0.4 s, afterwards with full speed (using a ramp of 0.1 s).The valve is half open for 0.9 s, afterwards full open (using a ramp of 0.1 s).
You may try to:
- drive the pump with variable speed and let the valve full open to regulate the volume flow rate of coolant
- drive the pump with constant speed and throttle the valve to regulate the volume flow rate of coolant
