内容記述 | The purpose of this study is to investigate characteristics of the turbulence generated by artificial disturbances composed of two sine waves. Different combinations of frequencies and phases were used to define the disturbances. Disturbances with randomly provided phases were fed to the 99 fans of a multi-fan type wind tunnel. A parameter n_d = f_i/Δf (i = A,B) was introduced, where f_i was the two selected frequencies, and Δf the difference between them. When n_d was an integer, peaks appeared in the power spectra of the turbulence at frequencies associated with Δf, but when n_d was a noninteger, more peaks appeared irregularly in the downstream direction. | |||||
