水平分布三气泡运动特性研究

THE MOVEMENT OF THREE BUBBLES IN HORIZONTAL DISTRIBUTION

  • 摘要: 为研究孔径、间距对三气泡运动特性的影响规律,本文利用高速相机和粒子图像测速仪观察三喷嘴气泡的运动过程,分析间距与孔径对三气泡的轨迹、速度、偏移量的影响,并与单气泡和双气泡进行对比,获得间距与孔径对气泡的影响规律以及流场对气泡的运动影响。实验结果表明,气泡数目的增多会使气泡运动轨迹更加复杂;气泡间距和孔径的增大或减小,对气泡的速度、流场、偏移量和运动轨迹都会产生影响。

     

    Abstract: In order to study the influence of the aperture and the spacing on the motions of three bubbles, a high-speed camera and the particle image velocimetry technology are used to study the motions of three nozzle bubbles. The effects of the spacing and the aperture on the trajectory, the velocity and the offset of the three bubbles are analyzed. Compared with the cases of a single bubble and two bubbles, the influences of the spacing and the aperture on the bubbles and the flow are determined, along with the effect of the field on the motion of the bubbles. The experimental results show that the increase of the bubble number will make the bubble trajectory more complex; the increase or decrease of the bubble spacing and the pore size will change the bubble velocity, the flow field, the offset and the trajectory.
