项目摘要
1. OBJECTIVE : This research objective is to develop a manganese nodules hydrolifting system with the cooperation of air-lift pump and jet pump, and consequently to contribute to the manganese nodules recovery system.2. APPROACH : In order to approach the above mentioned objective, the following phases were organized. (1) A numerical simulation for the lifting characteristics for water with an air-lift pump. (2) Introduction of basic equations for gas-liquid-solid three phase flows. (3) Establishment of a method to classify the flow patterns of the three phase flows in a vertical pipe. (4) Investigation on the lifting characteristics for water under the cooperation of air-lift pump and jet pump.3. RESULTS : (1) In order to appreciate the lifting characteristics for water with the air-lift pump with the numerical simulation, it is necessary to obtain the correlations concerning with the drift velocity and the ratio of the pressure loss for gas-liquid flows to the one for liquid flows. A … More s the results of this simulation, the presented simulation proved to be accountable for the experimental results which were obtained through the apparatus with a 200m length lifting pipe at National Research Institute for Pollution and Resources. (2) One dimensional basic equations for three phase flows were presented with taking into account the radial distribution of the material mass elements. In application of these equations, the constructive equations were also required, which included the parameters such as drift velocity, mass distribution, wall shear stress and heat flux. (3) Three phase flows in a vertical pipe were classified by means of the relationship between the probability density distribution function of differential pressure fluctuations and flow patterns. It is demonstrated from this above relationship that a single-peak distribution and a bi-peak distribution indicate the bubble flow and the slug flow, respectively. This difference among these distributions enables to objectively classify the flow patterns. (4) The lifting characteristics for water under the cooperation of air-lift pump and jet pump were experimentally investigated, and the effects of the connecting order of these pumps on the characteristics was examined. As a results, it was confirmed that the system of air-lift pump-jet pump achieved higher efficiency in the lifting characteristics for water than the one of jet pump-air lift pump. Less
1. 目的:本研究的目的是开发一种气升泵和喷射泵配合的锰结核水力提升系统,从而为锰结核回收系统做出贡献。 2.方法:为了实现上述目标,组织了以下阶段。 (1)气力泵提升水特性的数值模拟。 (2)介绍气-液-固三相流的基本方程。 (3)建立了垂直管道内三相流流型分类方法。 (4)气升泵与喷射泵配合下水的提升特性研究。3.结果:(1)为了通过数值模拟来了解气升泵对水的提升特性,需要获得气液流与液体流的漂移速度和压力损失比值的相关性。作为该模拟的结果,该模拟被证明与通过国家污染与资源研究所的 200m 长提升管设备获得的实验结果相符。 (2)考虑了物质质量元素的径向分布,提出了三相流的一维基本方程。在应用这些方程时,还需要构造方程,其中包括漂移速度、质量分布、壁面剪应力和热通量等参数。 (3)利用压差脉动概率密度分布函数与流型的关系对垂直管道内三相流进行分类。从上述关系可以看出,单峰分布和双峰分布分别表示气泡流和段塞流。这些分布之间的差异使得能够客观地对流动模式进行分类。 (4)对气升泵和喷射泵配合下的水提升特性进行了实验研究,并考察了泵的连接顺序对其特性的影响。结果证实,气升泵-喷射泵系统在水的提升特性方面比喷射泵-气升泵系统实现了更高的效率。较少的
