内容記述 | The aerodynamic sound generated from a protuberance has been simulated in this study. The protuberance, which is placed on a flat plate, has three kinds of shape at the leading edge. The propagation of sound waves is examined by solving the three-dimensional N-S equations to observe small pressure fluctuations both in the near and far fields. Numerical results show that vortices created from near the leading edge may make pressure waves, leading to acoustic waves. Moreover, FFT analysis shows that the frequency profile partly agrees with experimental data. | |||||
