A flow distribution method and apparatus is set forth for reducing noise and vibration immediately downstream of a noise creating device such as a partially open or closed valve element. Partially open valve elements typically create a quarter moon distribution of highly turbulent flow. The present apparatus contemplates positioning of the inlet ends of a plurality of tubes immediately downstream within the flow region of the quarter moon area to gather the turbulent flow into a plurality of small tubes. The tubes are routed along a pipe section to different areas or points in the cross sectional area to discharge the flow. The several tubes collectively smooth the fluid flow through the structure. A method is also set forth. In one alternate embodiment, the downstream end of the pipe section is larger than the inlet end, and in another version, the individual tubes are provided with enlarged outlet ends.
