Description

The component Throttle is a model of a fluid resistance with to a large extent linear shaped dependence of the VolumeFlow on the pressure difference pA-pB connected to the component.

It is parameterized by the geometric parameters Diameter and Length. The kinetic viscosity of the fluid and its density are considered in their temperature dependency.

The Throttle is suitable for modeling a bore, if the ratio of its length l to its diameter d is comparatively large (approx. l/d > 10). It does not take any inductance into consideration. If desired, a PipeWithoutCapacity or a Pipe is the correct component instead.
