  “短路流”译为未确定词的双语例句
    Although the geometric structure of a hydrocyclone is simple, the fluid flow field in it is very complicated, generally there exist inner and outer helical flows, a circulation and short-circuit flows and an air core.
    虽然它的结构不复杂,但它的内部流场却非常复杂,一般认为存在内旋流、外旋流、短路流和循环流。
短句来源
    One of effective measures to weaken short-out flow is to set up an eccentric gas exhaust duct.
    指出设置偏心内筒是减小短路流的有效措施之一。
短句来源
    The principal conclusion is that there existed serious short circuiting and back mixing flow in the Performax coalescer,despite it has been recognized as new industry standard for oil water separation.
    结果表明 ,Performax填料虽有助于强化设备的分离特性 ,但不能显著改善流动特性 ,在下游流场中仍存在短路流和返混流现象。
短句来源
    We have also predicted the phenomena affecting the separation efficiency--the up ash loop, the short circuit of exhaust duct and the return confusion of eject dust duct. All this makes for a better understanding of the separation mechanism of cyclone separator, and forms the basis for the further theory and experiment study on the cyclone separator.
    另外,还模拟出了上灰环、排气管短路流及排尘口返混等影响分离效率的几种现象,为进一步研究旋风分离器的分离机理理论及实验研究打下基础.

  short flow
We define edges to be local or global depending on the size of the maximum short flow between the edge's endpoints.
      
Here, a short flow, or alternatively an ?-short flow, is one composed of paths whose length is at most some constant ?.
      
We present fast approximation algorithms for the maximum short flow problem and for testing whether a short flow of a certain size exists between given vertices.
      
A short flow path, for example to the sea bed, means that the carbon dioxide may not be confined for geological periods of time.
      
As these cavities are carried a short flow is known as water hammer.

Flow fields in PV type cyclone separators are meansured by means of five hole pitot tube and hot wire anemometer. The influences of inlet velocity V i and main configuration dimensions on flow field are shown,which give a solid base for scaling up of cyclone separator. It is noticed that there are several secondary flows that decrease the separation efficiency. They are secondary flow in the spiral inlet,short circuit stream and the flow...

Flow fields in PV type cyclone separators are meansured by means of five hole pitot tube and hot wire anemometer. The influences of inlet velocity V i and main configuration dimensions on flow field are shown,which give a solid base for scaling up of cyclone separator. It is noticed that there are several secondary flows that decrease the separation efficiency. They are secondary flow in the spiral inlet,short circuit stream and the flow into the dust hopper.

用五孔球探针与热线风速仪测定了不同结构参数的PV型旋风分离器全空间内的三维速度分布,总结了入口气速与主要结构参数变化后对流场的影响规律,提出了相似放大的办法。结果表明,在旋风分离器的蜗壳顶部存在纵向二次流,在芯管下口附近存在短路流,在排尘口处有较强的灰斗返气,这些均不利于气固分离

The 2 D & 3 D flow dynamics of three typical separators were investigated with the particle image velocimeter(PIV)and residence time distribution(RTD)techniques,which were the Performax coalescer of C E Natco Company,HNS Ⅱ separator of Henan Oilfield of CNPC and a novel separator proposed by the author.The principal conclusion is that there existed serious short circuiting and back mixing flow in the Performax coalescer,despite it has been recognized as new industry standard for oil water separation.An...

The 2 D & 3 D flow dynamics of three typical separators were investigated with the particle image velocimeter(PIV)and residence time distribution(RTD)techniques,which were the Performax coalescer of C E Natco Company,HNS Ⅱ separator of Henan Oilfield of CNPC and a novel separator proposed by the author.The principal conclusion is that there existed serious short circuiting and back mixing flow in the Performax coalescer,despite it has been recognized as new industry standard for oil water separation.An improved flow pattern has been achieved by measuring the emulsion flowing in HNS Ⅱ separator,due to the utilization of corrugated plate pack and the opening of the feed inlet reached the water phase under the water oil interface.Its hydraulic behavior is not in good order because there still some volume does not come into play.The novel separator not only used the effective structures in reference to the above two devices of HNS Ⅱ,but also introduced two new components which were specially used for the flow stabilization and coalesce enhancement,so both hydraulic and separating behaviors improved further.The results of PIV and RTD showed that the flow pattern in the novel separator was very similar to the slug flow.The proposed new separator performed the best hydraulic behavior among the three separators investigated in this work.

采用粒子图象测速 ( PIV)与停留时间分布 ( RTD)检测技术 ,对美国 C-E Natco公司的 Performax聚结器、河南石油勘探局的 HNS- 分离器和作者最近开发的一种重力式油水分离结构优化设备的流动特性进行了二维和三维条件下的模拟实验研究。结果表明 ,Performax填料虽有助于强化设备的分离特性 ,但不能显著改善流动特性 ,在下游流场中仍存在短路流和返混流现象。由于采用多组波纹填料和改进了进液方式 ,HNS- 型分离器的流动特性较 Performax聚结器有所改善 ,但在流场的一些局部区域中仍有返混现象 ,设备的有效空间未能得到充分利用。而重力式油水分离结构优化设备 ,在继承前两设备成功结构的同时 ,还进一步引入了新型稳流与聚结构件 ,大大改进了设备中的流动条件 ,使流场分布更加均匀稳定 ,从而为提高设备的综合技术经济性能提供了技术保障
