annular gap 中文意思是什麼
annular gap
解釋
環形間隙-
The gas - flow in the annular cross section is study, and it is clarified that in such a physical model when rotor is rotating at high speed, the nature - flow is restrained by rotating - flow, so the actual 3d gas - flow field in the wedge - shape air - gap can be simplified to an axial symmetric quasi - 3d gas - flow field
通過對環形橫截面內二維氣隙流場的研究，說明在本文研究問題中，旋轉流對自然流具有強烈的抑制作用，從而將實際上的三維流場簡化為軸對稱準三維流場進行研究。 -
In this paper, the characteristics and details of the laminar flow fields in the annular gap of the modules were theoretically studied by numerical simulation method first time. the mechanism of the microfiltration with outside helical flow was analyzed. its results were compared with the former experimental results and those of outside axial flow mf and would provide the theoretical basis for optimization design
本文採用數值計算的方法首次對層流范圍內膜器環隙內的流場進行數值模擬，從理論的角度分析其流場分佈的細節和特點，與前人的實驗研究結果和外軸向流微濾進行比較，分析外旋流強化微濾的機理，對膜器優化設計提供理論依據。 -
So it should be pointed out from the above analysis that to make the module operate better, it is the better choice to ensure the flow in the annular gap of it to be a turbulent flow
同時也需指出的是，為使外旋流的方式較好地達到強化微濾的目的，建議採用一定流量下的湍流方式較為合適。
