N2 - Side branch resonance can cause standing waves in the main line. The main line standing wave modifies the acoustic boundary condition between the side branch and the main line, This interaction leads to drift in the side branch resonant frequency, and to sensitivity in the side branch and main line resonant amplitude as a function of branch position along the main line standing wave. In many cases the mainline standing wave is not stationary, leading to temporal modulation of the side branch frequency and amplitude. These features are examined using novel signal interrogation techniques that expose frequency and amplitude variation in time, Data from a low pressure air test facility are used to reinforce the theory and demonstrate the system behavior, Finally, the connection between the dynamic pressure signal features and methods for main line and branch component endurance prediction is developed, Components such as steam dryers, safety relief valves, and heat exchangers would be candidates for endurance prediction using these methods.
