abstract

We measured the aerodynamic noise generated from an inclined circular cylinder with endplates in experimental conditions using a low noise wind tunnel. The inclination-angle dependency of the aerodynamic sound is related to the aspect ratio A that is the ratio of the distance between the endplates to the circular cylinder diameter. To analyze the dependency in detail we derived the correlation length from the velocity fluctuation in the wake. As a result, when the inclined angle changed from 0 degrees to 20 degrees, the correlation length got smaller at A = 10. On the other hand, in the case of A = 30, the correlation length got longer. So we visualized the flow around the cylinder using numerical simulation and the hydrogen bubble method in order to analyze these phenomena.
