modelPartialFlowCoefficient
Partial model describing base flow coefficient
Information
This is a base model for flow coefficient models that are required
for expansion valves. It defines some basic inputs and outputs that
are commonly used by flow coefficient models presented in
AixLib.Fluid.Actuators.Valves.ExpansionValves.Utilities.FlowCoefficient.
These inputs and outputs are summarised below:
