A planar cyclone is designed for visualizing bubbles in the cross‐section of a degassing hydrocyclone. The pressure distribution is studied through a series of experiments and Reynolds stress model simulations. The velocity distribution of the planar cyclone mostly exhibits the quasi‐forced vortex zone and boundary layer zone. The bubble dynamics are simulated using both Euler‐Euler and Euler‐Lagrange approaches, and the output is compared with the imaging results. The Euler‐Euler simulation provides more accurate predictions of the bubble trajectory. The histograms of residence time and traveling distance given by the Euler‐Lagrange approach exhibit a reasonably regular pattern. With higher values of the inlet Reynolds number, stronger forces acting on the bubbles lead to a decreased but more uniform residence time. © 2018 American Institute of Chemical Engineers AIChE J, 64: 2689–2701, 2018

平面旋风分离器中的气泡分离动力学：实验和CFD模拟

平面旋风分离器设计用于可视化脱气水力旋流器横截面中的气泡。通过一系列实验和雷诺应力模型仿真研究了压力分布。平面旋风分离器的速度分布主要表现为准强迫涡旋带和边界层带。使用Euler-Euler和Euler-Lagrange方法对气泡动力学进行仿真，并将输出结果与成像结果进行比较。Euler-Euler仿真提供了更准确的气泡轨迹预测。欧拉-拉格朗日方法给出的停留时间和行进距离的直方图显示出合理的规律性模式。入口雷诺数越高，作用在气泡上的作用力越大，停留时间就越短，但停留时间越均匀。AIChE J，64：2689–2701，2018
