Post Mixing Optimization and Solutions

Keith Johnson

Keith is our source for mixing CFD. Have a look at the CFD area of the Mixing Forum for several examples of what he can do. Keith is using Acusolve and has been able to derive the power number of each mixing application within a few percentage points. He was even able to predict the head-, flow-, and power-numbers of a solvent extraction pumper within a percentage point. This allows us to describe the effect of solvent extraction mixing without the need to refer back to experiments. Together, we have validated the Acusolve CFD program for this liquid-liquid continuous flow application. More on our CFD capabilities can be found in the Services and Products area of Post Mixing. Examples of our work can be found in a table with links in the CFD area.

Tom and Keith first met in Early 2000 at Dantec in NJ. They have been in contact ever since. As of summer 2003 they have worked on several publications together (Process Intensifier Characterization) and Keith has put some action into this website with his CFD animations. He has even converted experimentalist Tom into a CFD believer.

Keith E. Johnson, P.E., is an independent consultant. Contact him through our Contact Us page and we will get you in touch.

His experience in engineering analysis, applications, development, and advanced solutions integration, spans over 30 years cumulatively in the fields of advanced high performance computational engineering analysis (CFD, solid mechanics, heat transfer), high performance computing industry, energy (power generation) industry, and automotive industry including various automotive CFD applications along with advanced engineering/research in both the tire and rim industries. In recent years he has been active in developing and supporting the application of advanced, high performance/productivity, GLS FE CFD tools for computational fluid mixing analysis.

Keith has earned a Masters Degree in Mechanical Engineering at the University of Akron in computational continuum mechanics (Masters Thesis in Nonlinear Finite Element Solid Mechanics), and did his undergraduate work in Mechanical Engineering at the University of Akron as well.

He is a registered Professional Engineer in Ohio, and is an active member of AIChE and associated with the North American Mixing Forum.
