流れの可視化によるスタティックミキサーの混合性能の定量化

抄録

Static mixers are simple devices for mixing fluids capable of saving space and energy in comparison with stirring tank systems. Many static mixers have developed and commercialized, while a new static mixer; MSE (Multi-Stacked Elements) static mixer has also developed in our previous work. Inadequate mixing conditions are frequently observed for complex fluids; however, it is difficult to evaluate the non-uniformity of mixed fluids. In this study, we have conducted flow visualization using a green laser sheet device and a high speed video camera to evaluate mixing performance for static mixers including MSE static mixer. Experimental study was conducted using viscous and/or poor compatible fluids to propose five indexes, which can express the ability of static mixers.
