在目前的工作中，创建了一种用于研究浓缩悬浮液的流变流动行为的在线超声波方法。它基于用于中试工厂和工业规模应用的无损流变测量技术。在其他地方，作者讨论了对暴露于压力驱动剪切流条件下的高浓度悬浮液进行在线流变学表征的巨大需求。大多数现有的在线方法都是基于破坏性的宏执行器，不适用于对变形结构敏感的材料。由于我们基本感兴趣的过程会影响悬浮液的结构，因此很难将流变测量的影响与工艺参数微调所产生的微弱结构变化分开。这些效应的大小通常与结构液体的复杂流动动力学相关，并且对移动流体周围的密度或温度波动敏感。
In the present work an in-line ultrasonic method for investigation of the rheological flow behavior of concentrated suspensions was created. It is based on a nondestructive rheological measuring technique for pilot plant and industrial scale applications. Elsewhere the author discusses a tremendous need for in-line rheological characterization of highly concentrated suspensions exposed to pressure driven shear flow conditions. Most existing on-line methods are based on destructive macro actuators, which are not suitable for materials with sensitive to applied deformation structure. Since the process of our basic interest influences the structure of suspension it would be difficult to separate the effects of rheometric measurement and weakly pronounced structural changes arising from a fine adjustment of the process parameters. The magnitude of these effects is usually associated with the complex flow dynamics of structured liquids and is sensitive to density or temperature fluctuations around the moving r...
