rotating flow meaning in English
旋转流
Examples
- Microfilltration within stationmary tubular membrane elements with rotating flow is one of the most efficient method to enhance crossflow microfiltration , but its flow field characteristics are far from understanding and its filtration characteristics are also had to reseach , because the rotating flow field are superposed by rotating shear flow and axial flow and radial permeate flow
旋转流静止管式膜微滤是十字流强化微滤的有效方法之一，但由于其受到旋转剪切流、轴向剪切流及径向渗透流的三维流场作用，其流场特性有待探索，其分离特性也有待深化认识。 - Fisrt , the flow field of radial and tangential annulus with rotating flow are made by using an advanced piv system , its flow field characteristics are obtained preliminary probed . it is found that the flow field characteristics are not the same between unpermeateing flow and have permeateing flow , otherwise the flow field is compared between rotating flow and dynamic tubular membrane
首先通过采用先进的piv测试系统，对旋转流膜器的径向环隙和切向环隙处的流场进行了实测，初步探讨了其流场特性，发现在无渗透流和有渗透流的情况下其流场并不相同，并与旋转动态膜的分离特性进行了比较。 - In this dissartation , by using the particle image velocemetry ( piv ) system and microfiltration of incompressible inorganic salt powder systemic investigation are made on the flow field of polyacrylate tubular membrane elements with rotating flow . it is compared the slurry inlet method between tangential and axial
本文通过piv激光测试系统首次对聚丙烯( pa )旋转流管式膜流场进行了实测，并利用sio _ 2进行分离实验，比较两种不同的切向进料方式对过滤与分离的影响，并与普通十字流过滤进行比较，提出了旋转流膜管的再生方式。 - Fourth , the membrane recovering method was found within stationary tubular membrane elements and was compared with rotating flow by using experiment , that is , the unloading pressure recovering method is one of the most efficient method , it may reduce the auxiliary time , such as washing , backflush , reverse filtration , but the tubular membrane is washed or backflush or changed after the cycle period are accumulated numerous times
第四、对旋转流静止管式膜的再生进行了实验比较，并提出了旋转流膜管可以通过卸压再生，以减少膜管每次使用后的冲洗、反吹等辅助时间，采用该种方法再生的膜管其渗透通量完全能满足要求，当循环使用一定次数后再进行或冲洗或反吹或更换新膜管。
