摘要： A liner system for a steam outlet pipe of a turbine bypass system comprises a liner mounted in spaced coaxial relation to the inner pipe wall such that an annular cavity is defined between the liner and the steam outlet pipe. The cavity is open on an upstream end and closed on a downstream end such that a quarter-wavelength resonator is formed for attenuating noise associated with a flow of superheated steam passing through the steam pipe. The liner may include a plurality of perforations to further attenuate noise in the steam outlet pipe. The open upstream end and closed downstream end of the cavity increases pressure within the cavity to prevent cooling water from entering the perforations and contacting the inner pipe wall. A wire mesh disposed against the outer liner wall may block cooling water penetration through the perforations and may further attenuate noise associated with the flow of superheated steam.
摘要翻译：用于涡轮旁路系统的蒸汽出口管的衬套系统包括衬套，其以与内管壁间隔的同轴关系安装，使得在衬套和蒸汽出口管之间限定环形空腔。空腔在上游端打开并在下游端封闭，使得形成四分之一波长的谐振器用于衰减与通过蒸汽管的过热蒸汽的流动相关联的噪声。衬套可以包括多个穿孔，以进一步减弱蒸汽出口管中的噪音。空腔的开放的上游端和闭合的下游端增加腔内的压力，以防止冷却水进入穿孔并接触内管壁。设置在外衬套壁上的金属丝网可阻止冷却水穿透穿孔，并可进一步减弱与过热蒸汽流相关的噪音。

摘要： A GN2 exhaust muffler. The GN2 exhaust muffler includes a first pipe and a second pipe. The first pipe has a first end and a second end. The first end of the first pipe is capped. The first pipe also includes a plurality of apertures that are positioned near the capped first end. The second end of the first pipe is adapted to receive a flow of GN2 exhaust. The second pipe encases a portion of the first pipe such that the capped end and the plurality of apertures are housed in the second pipe. Moreover, the second pipe has an exhaust outlet adapted to output the GN2 exhaust.
摘要翻译：一个GN 2排气消声器。 GN＆lt; 2＆gt;排气消音器包括第一管和第二管。第一管具有第一端和第二端。第一根管子的第一端被盖上。第一管还包括位于封盖的第一端附近的多个孔。第一管的第二端适于接收GN 2排气的流动。第二管道包围第一管道的一部分，使得封盖端部和多个孔口容纳在第二管道中。此外，第二管具有适于输出GN 2排气的排气口。

摘要： High energy loss fluid control is attained by subdividing flow of high pressure fluid into a plurality of individual streams in respective passageways having a long length to diameter ratio to impart high frictional resistance losses to the fluid flow, the passageways being in and between laminar surfaces and configurated along their lengths. For extremely high efficiency the passageways are in labyrinth formation.
