Effect of Particle Concentration on Dynamic Characteristics of Oil Containing Particles

  • 摘要: 为了控制油液中颗粒物,降低对设备运行的危害,基于液固两相流的连续介质理论建立了含悬浮颗粒油液的伪均质流数学模型,研究悬浮颗粒油液的动态特性;利用所建模型对不同颗粒浓度情况下油液的速度、压力以及颗粒物的速度、浓度分布进行分析.研究结果表明,特征线法求解结果与实验数据吻合较好;油液速度、压力的跃变幅值随着颗粒浓度增大而减小,颗粒速度、浓度随着浓度的增大而增大;颗粒浓度分布受油液压力影响较大;伪均质流在管路始端、中段、终端发生跃变时刻分别为1/4脉动周期的奇数倍、1/8脉动周期的奇数倍和1/4脉动周期的偶数倍.
