| 摘 要： | 针对深水油气田主动旋流分离器强制涡流前推段锥度对分离性能的影响进行研究,应用RSM(reynolds stress model)湍流模型对主动旋流器内部强旋流场进行数值模拟计算,在强制涡流前推段锥角变化时,合理预测并对比其内部轴向速度、切向速度、离心力以及分离效率的变化。研究表明在一定范围内,前推段锥度的增加可以提高混合液在前推段内的轴向速度和切向速度,进而可以获得更高的分离效率。当锥角达到15°时,可以获得最为理想的分离效果。此外,在不同深水环境下对该主动旋流分离器进行仿真计算表明,不同的环境压力对旋流器分离效率影响很小。

| Abstract: | Subsea production system of deep-sea oil-gas field is one of the key technologies for oil companies to exploit oil reserves.In this paper,RSM turbulence model is applied to simulate the effect of the cone dimension of forced vortex on hydrodynamic performance of the dynamic hydrocyclone,and to study the separation efficiency in different deep-sea environment.Axial velocity,tangential velocity of the liquids and centrifugal force are predicted successfully by this numerical simulation.Comparisons of flow fie... |
