Part 1: Analysis of Existing Dynamic Pipeline Mixers or Line Blenders

Before you can optimize any mixing system, you first need to know what's mixing currently. We embarked on a study of 4 currently commercially available pipe mixers or inline mixers. Because the line mixers are inside the pipe, they are the mixing version of a black box. Do they really mix? Are they any good at what they do? What are they doing right? What could they be doing better? How do you use CFD or CFM to determine the goodness of mixing? What can a good CFD tool, especially made for mixing, reveal in the fluid mixing world? The answers to these questions are found in Part 1.

Part 2 : Optimized Process Intensifier - or - How to mix continuously and efficiently

Just like any mixing application, you need to know what the process wants. Jim Oldshue is famous for saying that, and its true. It still holds the same for mixing in a pipe. Sure, brut force will work in most instances, but it can be done elegantly, too. This is the ultimate in continuous mixing. For the first time in over 35 years, this great and inexpensive work horse of the mixing industry gets a make-over. And you will we surprised at the the resultant mixer designs. Sure you are anxious, but make sure you read or gaze at Part 1 first before looking at the answers.

If you want to go through this in order, there will be a link at the bottom of each page bringing you to the text topic, or bringing you back to this spot, the title page (just in case you get lost and don't know where you are anymore). Topics at the same level are also listed in the navigational links at the bottom of each page. Sub-topics of any topic are always found under the banners at Post Mixing.
