In the era of new process technologies such as biological transformations and nano-science, many of the old technologies are presumed to no longer be important. This is certainly not true of fluid mixing. Both high tech and low tech process industries need some knowledge of mixing, whether for dispersing nano-particles or feeding oxygen and nutrients to micro-organisms. Even in this new century, the starting engineer and the more experienced engineer will encounter mixing problems with significant frequency.

Fluid mixing deals with complex processes, involving multiple phases in complex geometries. It is a topic barely mentioned in a typical engineering curriculum, yet often referred to in the manufacturing world. In the process of scaling up from a small unit to a larger one, fluid mixing still plays a dominant role. It is a topic chemical engineers need to understand, and learn to master.

In this webinar, we introduce key concepts in fluid mixing, and discuss the range of equipment geometries that are involved. We also discuss the resources available for helping the practicing engineer solve many mixing problems.


Dr. Arthur William Etchells III

Dr. Arthur William Etchells is a world recognized authority in the field of mixing for the process industries. He is a chemical engineer with BS and MS degrees from the University of Pennsylvania, and a doctorate from the University of Delaware.  For thirty nine years he worked for the DuPont Company, primarily as an internal consultant for the many diverse DuPont businesses in the field of fluid flow with emphasis on mixing and slurry transport. He has achieved the highest technical level of DuPont Fellow and the highest technical award, the Lavoisier Medal.
