The Degeneration of Artifical Disturbing Signal in Turbulent Boundary Layer
Likun Wang · Journal of Experimental Mechanics · 1999
Artificial disturbance is introduced to an experimental wall turbulent field. The degeneration of the artificial disturbing signal in stream and normal directions of the layer is studied by using power spectrum analysis. The degeneration trend of artificial disturbance in turbulent boundary layer is obtained for different disturbing frequencies.
