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:

"Inputs and outputs" border="1" cellspacing="0" cellpadding="2" style="border-collapse:collapse;">
Type Name Comment
input AVal Cross-sectional area of the expansion valve
input dInlPip Diameter of the pipe at valve's inlet
input opening Valve's degree of opening
input staInl Thermodynamic state at valve's inlet conditions
input staOut Thermodynamic state at valve's out conditions
input pInl Pressure at valve's inlet
input pOut Pressure at valve's outlet
output C Flow coefficient
