Abstract EN
Data from a low pressure air test facility are used to quantify the influence of the acoustic field in the main line on side branch resonance behavior.
The main line of diameter D = 7.6 cm may accumulate acoustic energy broadcast from a resonating branch of diameter d = 1.9 cm (d/D = 0.25).
The side branch resonance amplitude is a strong function of branch position along the main line with the normalized pressure rising to 1.2 in the most favorable branch positions with Strouhal number near 0.3.
Large time variation of the side branch and main line resonance amplitude is apparent for most branch positions.
A moving window is used on the time history to collect an array of power spectral densities (PSDs).
Peak amplitude values from the PSD array are represented in a probability density function (PDF) that provides a repeatable characterization of data from the system.
