In the turbulent wake behind an upstream cylinder in a uniform flow, the downstream cylinder was set in the form of an intersection with the upstream cylinder. It was found that the acoustic radiation from the two circular cylinders forming an intersection was far smaller in comparison with that of a single cylinder. The variation of the acoustic radiation was measured by varying the intersectional angle of the two cylinders, the point of mutual contact and the angle between the downstream cylinder and the uniform flow. Moreover, the pressure distributions around both cylinders were measured. The flow pattern has been verified by oil-film and smoke-wire flow visualization. Then, the relationship between the flow and the noise generation was studied.
