Description

The VanneReglante block represents a variable orifice control valve. The flow rate through the valve is proportional to the valve opening.

ΔP × h × |h| = k × Q × |Q|

where h is the valve opening, ΔP is the pressure difference, and Q is the flow rate. This model is only used for the laminar flow regimes. k is a constant depending on the valve geometry and mass density of fluid.

Parameters

• Cvmax

  Cvmax (maximum opening of the valve)

  Properties : Type 'vec' of size -1.

• p_rho

  Fluid density

  Properties : Type 'vec' of size -1.
