abstract = {<p style="text-align: justify;">When gas flows through corrugated pipes, pressure waves interacting with
vortex shedding can produce distinct tonal noise and structural vibration. Based on
established observations, a model is proposed which couples an acoustic pipe and self-excited
oscillations with vortex shedding over the corrugation cavities. In the model,
the acoustic response of the corrugated pipe is simulated by connecting the lossless
medium moving with a constant velocity with a source based on a discrete distribution
of van der Pol oscillators arranged along the pipe. Our time accurate solutions exhibit
dynamic behavior consistent with that experimentally observed, including the lock-in
frequency of vortex shedding, standing waves and the onset fluid velocity capable of
generating the lock-in.</p>},
