Description
The component Orifice is a model of a sharp-edged fluid resistance with a - to a large extent - root-like relationship between the flow rate and the pressure difference pA - pB acting on the component. The flow rate is independent of the viscosity of the hydraulic fluid.
It is parameterized by the geometric parameters Diameter and Flow Coefficient alphaD.
The Orifice is suitable for modeling an orifice opening, if the ratio of its length l to its diameter d is comparatively small (approx. l/d < 1.5).
The density of the hydraulics fluid is considered.
