circulation flow meaning in English
循环流动
Examples
- Constant circulation flow pattern
等环量流型 - The distributions of the residual flow and the residual discharge from the numerical model show that the residual circulation flows around the sandbanks contribute significantly to the deposition at the peak of sandbank , and closely related to the sandbank development
另外还研究了辐射沙脊群海域的余流及余流量的分布，发现在潮流沙脊两侧存在平面余环流，余环流将有利于泥沙在脊顶沉积，与潮流沙脊的维持发育密切相关。 - The existence of the asymmetrical residual transverse circulation flows in pair is discovered in the residual vorticity field along the passage and sandbank cross section . the transverse residual circulation flow is favorable to sediment ' s moving to the peak of sandbank and the development and maintenance of sandbank
首次发现，在潮涨潮落过程中，深槽中及沙脊两侧均存在一组方向相反、不对称余涡度场(余环流场) ，横向余环流的存在将有利于沙脊两侧的泥沙均向沙脊顶运动和堆积，是潮流沙脊的形成和维持重要动力因素。 - At a certain moment of mixing and stiring , every group a copy of circulation flow and spread is distributed to begin to go on at the micro level , mixing and stiring the sport characteristic that the speed not merely depends on the supplies , depend on structure rheology characteristic , particle big or small , alternate superficial size and is it form value of strength , etc
拌和到某一时刻后，各组份循环流动与扩散分布开始在微观水平上进行，拌和速度不仅取决于物料的运动特点，而且取决于物料的结构流变特性、颗粒大小、相间表面的大小和粘结力的值等。 - In this paper . flow properties of multistage fluidized - bed bioreactor with external circulation at a pilot scale is studied . according to characteristic analysis , the model of completely mixing reactor in series is introduced to characterize real reactor as a theoretical model . on the basis of analog computing analysis and discussion of theoretical model . by means of pulse tracer method , experiments on residence time distribution ( rtd ) have been done in different conditions including the change of tracer level , feeding flow rate and circulation flow rate . the result shows when the ratio of circulation flow rate and feeding flow rate amounts to at least 4 , the flow properties of multistage fluidized - bed bioreactor with external circulation at a pilot scale is very close to the model of completely mixing reactor in series . an amendatory model has been established by the regression method
作者首先在对反应器进行特征分析的基础上，建立了描述中试规模多级外循环流化床生物反应器流动特性的串级全混流模型，并对理论模型进行了模拟计算分析和讨论，在此基础上，作者分别在无循环和有循环(改变示踪剂用量、流加流量和循环流量)的条件下，利用脉冲示踪法对一到五级串联外循环流化床反应器进行了停留时间分布实验，结果表明，在循环流量与流加流量的比值达到大于等于4时，中试规模多级外循环流化床反应器的流动特性接近串级全混流模型，通过数据回归拟合的方法，建立了中试规模一到五级串联外循环流化床反应器的流动模型。
