Angles of peak sound radiation from axisymmetric duct inlets

The radiation of isolated spinning modes from five axisymmetric duct inlets having very different contours is examined experimentally in the absence of flow. It is found that when a mode is well cuton (cuton ratio ξ ≫ 1), the radiation pattern is much the same as if the duct were terminated at the i...
