This package contains component models for fixed flow resistances. By fixed flow resistance, we mean resistances that do not change the flow coefficient
k = m ⁄ √ΔP.
For models of valves and air dampers, see AixLib.Fluid.Actuators. For models of flow resistances as part of the building constructions, see AixLib.Airflow.Multizone.
The model AixLib.Fluid.FixedResistances.PressureDrop is a fixed flow resistance that takes as parameter a nominal flow rate and a nominal pressure drop. The actual resistance is scaled using the above equation.
The model AixLib.Fluid.FixedResistances.HydraulicDiameter is a fixed flow resistance that takes as parameter a nominal flow rate and a hydraulic diameter. The actual resistance is scaled using the above equation.
The model AixLib.Fluid.FixedResistances.LosslessPipe is an ideal pipe segment with no pressure drop. It is primarily used in models in which the above pressure drop model need to be replaced by a model with no pressure drop.
The model AixLib.Fluid.FixedResistances.Junction can be used to model flow splitters or flow merges.
