Rifled or other pipe wall corrugation may change the flow from a hetero-generous to a homogeneous regime by introducing a secondary circulation. 在有来复线的或其它的管壁皱纹的管中,由于引起副流,可能将非均质流转变为均质流。

Small performance hall: the whole performance platform is nearly surrounded by audience. The irregular corrugation of inside wall prevents the focus of sound wave. Audience will share the common space. 小演奏厅:观众几乎围绕着整个演奏台。内壁不规则的波状形式避免声波的焦点。观演者将分享这个共有的空间.在这个空间里,即使原创音乐,也会给人以新兴音乐的感动。
