RUI: Path instabilities of air bubbles rising in fluids

abstractcts - 0121340 m。吴，西方学院建议开展实验研究，以扩大我们对液体中气泡上升路径不稳定性的物理机制的理解。这种运动在许多工业过程和地球物理现象中都遇到过。PI建议开发一种新的三维成像系统，可以精确测量不稳定点附近的气泡轨迹。一些初步实验结果表明，随上升速度的不同，有两条不同的上升路径。通过三维成像系统，可以获得更准确的数据。

AbstractCTS-0121340M. Wu, Occidental CollegeIt is proposed to carry out experimental studies to extend our understanding of the physical mechanisms responsible for the instabilities in the path of rising air bubbles in a liquid. Such motion is encountered in a number of industrial processes and geophysical phenomena. The PI proposes to develop a novel three-dimensional imaging system that would allow precise measurements of the bubble trajectories in the neighborhood of the instability point. Results of some preliminary experiments show two distinct paths of rise depending on the rising velocity. It is expected that with the 3D imaging system, more accurate data will be obtained.
