modelPressureDropWithVaryingFlowCoefficient
Validation model for flow resistances with a varying flow coefficient
Extends from Modelica.Icons.Example (Icon for runnable examples).
Information
Before 0.5 seconds, the flow rates of the fixRes (pressure
resistance with a constant flow coefficient) and the varRes
(pressure resistance with a varying flow coefficient) are the same with the
identical pressure drop.
After 0.5 seconds, the flow rate of the varRes is lower than
that of fixRes as the flow coefficient
of the former decreases by √2.
