Ser Flow Cont $—$ Series flow control valve

The Ser Flow Cont component describes a series flow control valve. If the demanded flow rate qdemand is in the working range of the valve, the conductance of the valve is calculated such that the demanded flow rate is achieved. The conductance of the valve is limited by GMax (that is, a wide open valve) and GMin (valve closed with leakage from A to B).

As no dynamic effects are modeled, the jump phenomenon does not occur.

The mass and flow forces are not included.

Use the modifier(s)

VolumeA(port_A(p(start=1e5,fixed=true)))

and/or

VolumeB(port_A(p(start=1e5,fixed=true)))

to set the initial condition(s) for the pressure of the lumped volume(s) $\left[\mathrm{Pa}\right]$.
