Characterization of Multiphase Flow in Air-Sparged Hydrocyclone Flotation by X-Ray Computed Tomography

为了对充气水力旋流器(ASH)进行测量和优化，提出了X射线CT的发展和应用。X射线层析成像此前主要应用于医学领域。发展多相流的校准标准和图像重建计算机层析成像是本研究的主要目标。另一个目标是将在灰分上获得的流动可视化与分离效率相关联。ASH是在NSF的支持下发展起来的，是一项产学合作研究活动。这项工作将促进我们对X射线多相流无损成像工具的理解，并将为一种相对较新的分离设备中的流动结构提供数据。

The development and use of X-ray computed tomography was proposed in order to perform measurements and optimize the air-sparged hydrocyclone (ASH). X-ray tomography was previously applied in medical area. Development of calibration standards and image reconstruction computer tomography for multiphase flow is the primary objective of the research. Another objective is to correlate the flow visualizations obtained on ASH with the separation efficiency. The ASH was developed with the support from NSF, as a industry-university cooperative research activity. It is expected that the proposed work will advance our understanding of the X-ray non-destructive imaging tool for multiphase flow, and will provide data on the flow structure in a relatively new separation equipment.
