Hydraulic torque converter is a kind of device that can transfer the power . it is widely used in automatic transmission of a car . when it is in using , it has axial displacement 液力变矩器是汽车自动调速装置中广泛应用的主要部件，它是利用液体作为工作介质来传递动力的一种装置，其内部能量转换和工作油的流动状态极其复杂。
This paper described a cold gas simulation of solid rocket motor with submerged nozzle . a two - dimension model with rectangular channel was designed , which can simulate different flow conditions at three periods after ignition 本文从冷流模拟的角度出发，设计了通道为矩形的含潜入喷管发动机冷流模型，可以模拟发动机工作过程中三个不同时刻的流动状态。
At the same time we may observe the distribution and dispersion of flame in cylinder resulting from the air motion . this may be the most direct method to open out the internal relationship among the flow , ignition and combustion . 4 目前三维螺旋进气道的数值研究绝大部分是在自然吸气状态下，即在相同的进气压力下，研究不同气门升程时的流动状态，从中找出内在的因果关系。
Abstract : based on the establishment of physical model , this paper used a two - dimensional calculation model to numerically calculate and analyzed the heat transfer process of the two - phase flow within the conduit of single evaporator in cpl 文摘:在建立物理模型和分析管内流动状态并列出基本流动方程的基础上，采用一个二维计算模型进行数值计算，求得管内汽-液相的速度和压力分布。
Based on the analysis of corrosion mechanism of naphthenic acid , the major factors affecting the naphthenic acid corrosion , including crude oil composition , operation temperature , fluid velocity and flow pattern , pressure and metallurgy of equipment materials , are discussed 通过对环烷酸腐蚀机理的分析，指出原油组成、操作温度、流速和流动状态及设备材质等是影响环烷酸腐蚀的重要因素。
The device consists of a single - phase flow test device , which can make a real simulation of the downhole working conditions and the flow of the liquid in the subsurface pump , and a miscible - phase flow test device , which can simulate various oil - gas ratios 这种装置由单相流试验装置和混相流试验装置构成，前者能比较真实地模拟井下的各种工况和抽油泵内液体的流动状态，后者可模拟不同的油气比。
Because the operation in water hydraulic valves is controlled by flow fluid and the pressure drop results from energy loss of flow fluid past valve channel , the flow state of fluid in valves becomes the most important factor for the operational property of valves 由于水压阀是通过控制流体流动来操作系统的，阀的压降也来自于流体流经阀道时的能量损失，因此阀内的流体流动状态就成为决定阀操作性能最为重要的因素。
All participants took off their shoes and socks and temperatures were monitored throughout the experiment . " when colds are circulating , many people are mildly infected but show no symptoms , " said professor eccles , whose findings are published in today s issue of family practice magazine 参与研究的加的夫大学的埃克勒斯教授表示： “当冷空气处于循环流动状态下时，很多人会轻微感染上各种感冒病毒，但并未表现出任何症状。
