Acoustic wave propagation in a toroid cavity carrying a steady flow
The Journal of the Acoustical Society of America(2022)
摘要
This paper presents an analytical study of acoustic wave propagation in a toroid-shaped cavity. The interior wall of the cavity is rigid and encloses a fluid driven into steady motion along its azimuth. The analysis will focus on acoustic excitation near the principle resonance frequency of the system. The impact of steady primary and secondary flow on the acoustic velocity potential flow-reverse symmetry is evaluated.
