| Résumé : |
This research analyzes generation and propagation of the acoustic waves in a compressible fluid due to interaction with an immovable solid body. The objective is to identify the process by which inlet-driven oscillations in a confined space lead to the formation of acoustic phenomena such as pressure waves, reflection, and resonance. A theoretical background was initially established by going through significant terms of fluid acoustics, like acoustic streaming, radiation pressure, and the Ffowcs Williams–Hawkings (FW-H) model. Numerical simulation was then performed through ANSYS Fluent, where time-dependent simulations were executed to determine the impact of parameters such as wavelength (λ), phase (φ), and cylinder radius (R). Mean pressure signals, SPL spectra, and FW-H. |
