RUI: Path instabilities of air bubbles rising in fluids

摘要CTS-0121340 M。吴，西方学院建议进行实验研究，以扩大我们的理解的物理机制负责的不稳定性的道路上上升的气泡在液体中。 这种运动在许多工业过程和地球物理现象中都会遇到。 PI建议开发一种新的三维成像系统，该系统将允许精确测量不稳定点附近的气泡轨迹。 一些初步的实验结果表明，两个不同的路径上升取决于上升速度。 预计通过3D成像系统，将获得更准确的数据。

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.
