Two way valve with linear opening characteristics
Extends from Modelica.Icons.Example (Icon for runnable examples).
Information
Test model for two way valves.
The instance valTab has a linear opening characteristics
based on a table, while valLin also has a linear opening
characteristics that is directly implemented in the model.
For practical applications in which valves with linear opening characteristics
are used, one should use valLin rather
than valTab as valLin is a more efficient
implementation.
This test demonstrates that both valves have, as expected, the same mass flow rate for the whole range of the opening signal.
The parameter filterOpening is set to false,
as this model is used to plot the flow at different opening signals
without taking into account the travel time of the actuator.
