提出了一种以水为主流，在湍流区进行流动显示实验，评价圆管静态混合器混合性能的简便方法。将荧光颜料、甘油、两种羧甲基纤维素溶液和菜籽油各自注入混合器的上游。测试三种静态混合器条件：1）无静态混合器; 2）Kenics型静态混合器;和3）多堆叠元件（MSE）静态混合器。使用激光和高速摄像机系统监测每种条件下混合器下游的混合趋势以及每种注射流体，以获得横截面图像。我们提出了合适的指数的基础上获得的图像定量评价静态混合器的混合特性。
We propose a convenient way of evaluating the mixing performance of static mixers used for round pipe by conducting flow visualization experiments under the turbulent region and using water as the main stream. A fluorescent pigment, glycerin, two carboxymethyl cellulose solutions, and rapeseed oil were each injected upstream of the mixer. Three static mixer conditions were tested: 1) no static mixer; 2) a Kenics-type static mixer; and 3) a multi-stacked elements (MSE) static mixer. The mixing trend downstream of the mixer in each condition and with each injection fluid was monitored using a laser and high-speed video camera system to obtain cross-sectional images. We propose suitable indexes based on the images obtained for quantitative evaluations of the mixing characteristics of static mixers.
