turbulence pump 解釋
渦流泵
  • turbulence : n. 1. （風等的）狂暴；激流（現象）。2. 騷亂，動亂；強橫。3. 【氣象學】亂流。
  • pump : PUMP ＝politically upwardly mobile personality 政治新星，政治上有望晉升人士。n （淺口無帶的）輕舞...
  1. It adopts reynolds time - average n - s equation and k - ? turbulence model to calculate the inner 3 - d viscid turbulence flow of centrifugal pump. in the unstructured grid, the governing equations are discretized with finite volume method based on finite element method. then the pressure correction method is used to carry out numerical calculation

    而後採用基於雷諾時均n - s方程與標準-湍流模型來求解離心泵葉輪內三維粘性紊流，在非結構化網格中，採用基於有限元的有限體積法對方程進行離散，用壓力校正法進行數值求解。
  2. Install 5 pipe diameters minimum downstream from pump discharge or elbows to avoid flow turbulence. flow straighteners may be required in extreme cases

    安裝在距離泵排泄口或彎管下游至少5倍管道直徑的地方，以避免產生水流擾動。在極端情況下，可能需要流向矯直裝置。
  3. With piv technology, the flow field was measured to judge the performance of pump sump. by analyzing the pictures of velocity, streamline, turbulent kinetic energy and vorticity, we found that the turbulence was bigger while the ratio of the runoff increased. and the vortices always appeared in the field where the runoff was small

    通過piv試驗，測量了封閉式水泵吸水室內部的流場，以研究該水泵吸水室的性能； （ 2 ）通過分析流速圖、流線圖、湍動能圖和渦量圖，發現了流量比越大，湍動越大，漩渦總是出現在流量較小的一側。
  4. The creative points of the thesis are as follows : （ 1 ） the thesis establishes turbulence boundary layer equation that contains centrifugal force in flow field of two - dimension boundary layer of centrifugal pump and gives its solution

    本文創新之處是： （ 1 ）在離心泵葉輪二維邊界層流場內，建立了包含離心力的湍流邊界層方程並給出了近似解。
  5. Computing about five work conditions of slurry pump, the fields of velocity, compression and turbulence intensity are obtained, and the pump performance curves are also achieved to check the computation credence. based on the results of flow fields, particle tracks in varied conditions are achieved by using lagrange method

    本文對渣漿泵的在5個工況下（包括設計工況）的清水流場進行了計算，得到了描述流場的速度、壓力、紊流強度等參數場的分佈情況，最後計算了泵的運行性能曲線來校核計算的可靠性。
  6. The paper adopts the first advance scheme to realize the fuzzy optimization control of oil feeding pump system and eliminates the turbulence generated by changing control ways

    最後採用第一種改進方案，實現了輸油泵系統的模糊優化控制，並且消除系統切換時的擾動。
