内容記述 | An edge tone is self excited sound, which is one of the important phenomena in subsonic aerodynamic noise. This edge tone problem is numerically simulated using two-dimensional thin-layer Navier-Stokes equations. The slit width of the jet is changed with the jet speed and the distance to the edge kept constant. Another condition corresponds to the experiment by Brown. With the certain grid resolution, acoustic propagation is well captured. The FFT analysis shows that the amplitude of the acoustic wave is influenced by the jet width and the frequency agree with Brown's experimental result. Although the computational result is qualitative as far, it indicates the future possibility of the numerical approach for understanding the mechanism of the edge tone problem. | |||||
