.ThermofluidStream.FlowControl.PCV

Information

This component can be used to emulate a pressure-drop or output-pressure regulated control valve, depending on the chosen valve mode.

Depending on the parameter mode, either the pressure at the outlet p_out or the pressure difference dp between inlet and outlet can be stipulated. This is done either by parameter pressure_set_par or via input connector pressure_set_var when setting pressureFromInput = true. The resulting mass flow will be determined by its usual dynamics.

Setting dp instead of p_out has advantages, when p_out is determined by a volume at the outlet (for instance an accumulator).

The pressure difference dp is normalized, such that it cannot create pressure and it is zero for zero or negative mass flow.
