Mixing in stirred tanks is vital to a wide range of industrial processes, typically requiring solids to be fully suspended and evenly distributed. The quality of suspension and mixing is typically measured visually. Such measurements are thus subject to human interpretation and can only feasibly be conducted in transparent systems – an uncommon condition in industrial systems. Visual measurements of homogeneity must also infer full 3D distributions of particles solely from the observation of a limited section thereof. This work details methods by which a system's homogeneity and state of suspension may be measured and quantified with no human interpretation, which can extract information from opaque systems and consider full 3D data acquired throughout the interior of a given system.

用于搅拌罐中液固混合的正电子发射粒子跟踪

搅拌罐中的混合对于广泛的工业过程至关重要，通常需要将固体完全悬浮并均匀分布。悬浮液和混合液的质量通常通过肉眼测量。因此，此类测量需要人为解释，并且只能在透明系统中可行地进行-这在工业系统中并不常见。均质性的视觉测量还必须仅从对其有限截面的观察中推断出颗粒的完整3D分布。这项工作详细介绍了无需人工解释即可测量和量化系统同质性和悬浮状态的方法，这些方法可以从不透明的系统中提取信息，并考虑整个给定系统内部获取的完整3D数据。
