中文摘要:
      为了优化超重力分离装置,课题组对其内部流场进行了研究。通过计算流体力学软件FLUENT对超重力分离装置填料内部的流体流动进行数值模拟,分析了转速、填料外径和丝网尺寸对流场的影响。结果表明:液相速度分布与气相速度分布一致,液相速度主要受气相的影响,与液相入口速度无关;同一转速下填料区气相速度由内向外逐渐增大,各位置的气相速度随转速的增大而增大;气相最大速度与转速和外径有关,与丝网的尺寸无关。数值模拟的结果对超重机的设计与优化有一定的借鉴意义。
英文摘要:
      In order to optimize the higee separation device, the research group carried out research on its internal flow field.The fluid flow inside the packing of the super gravity separation device was numerically simulated by computational fluid dynamics software (FLUENT), and the influence of the rotational speed, the outer diameter of the packing and the size of the wire mesh on the flow field were analyzed. The results show that the liquid phase velocity distribution is consistent with the gas phase velocity distribution. The liquid drop velocity is mainly affected by the gas phase and has nothing to do with the liquid phase inlet velocity. At the same rotation speed, the gas phase velocity of the filler zone gradually increases from the inside to the outside, and the gas phase velocity increases with the increase of the rotation speed; the maximum velocity of the gas phase is related to the rotational speed and the outer diameter, regardless of the size structure of the mesh. The results of numerical simulation have certain reference significance for the design and optimization of overweight machine.
