摘要
本文开发了一种集高速视频分析系统和计算机数字图像处理技术于一体的具有普适性的动态高速CCD摄像系统,并利用该系统测定了两相三维下喷环流反应器内的环隙气泡行为,考察了不同喷咀和操作条件对气泡行为及平均传质比表面积的影响.实验结果表明这是一种可准确测量气泡状态参数的快捷方法,并可作为其他内置气泡测量方法的标定依据.
The dynamic high-speed CCD photographic measurement system has been developed, which covered the techniques of high-speed vision analysis system and computer disposal system of digital images. The behaviour of bubbles in annular regions of the two-phase three-dimension downward-jet loop reactor has been measured under various geometrical characteristics and working conditions. The results show that it is a rapid method to measure precisely the bubble parameters and can also be a standard of other bubble measurement methods in which probes are placed in the reactor.
