CHICAGOLAND PHARMACEUTICAL DISCUSSION GROUP
Affiliated with the American Association of Pharmaceutical Scientists

There are many different mixing processes occurring concurrently in the pharmaceutical industry.  This talk will discuss these many processes.  Examples are solid suspension, blending, gas-liquid mass transfer and heat transfer.  The object is to select the right mixing configuration to optimize the process, increase yield, and reduce by-products.  The spectrum of impellers will be analyzed to select the best impeller for the process.  New tools to assist in this process will be shown.  Examples are Laser Doppler Velocimetry and Computational Fluid Dynamics.  Physical mixing characteristic for Blending, Gas-Liquid, Solid Suspension and Mass Transfer will be shown.  The importance of the flow structures using Computation Fluid Dynamics and Scale-Up will be emphasized.

Dr. Ronald J. Weetman, Senior Research Scientist at LIGHTNIN, earned a B.S. from Lowell Technological Institute, a M.S. from MIT and a Ph.D. in Mechanical Engineering from the University of Massachusetts.  He has 21 patents and is the author of 38 publications including contributions to Fluid Mixing Technology by J.Y. Oldshue.  Over the last 25 years he has specialized in theoretical, computational, and experimental fluid mechanics as applied to mixing technology. Dr. Weetman developed the first industrial automated Laser Doppler Velocimeter laboratory in 1976.  He has invented various types of impellers that cover a broad range of mixing applications.  Currently twelve of these impellers are being produced at LIGHTNIN; which represents approximately 75% of the impellers LIGHTNIN currently produces.  Dr. Weetman has also designed unique methods of forming his impellers to optimize manufacture while maximizing process gains.  He was named Inventor of the Year in Rochester, NY for 1989. He was chairman of Mixing XIV, NAMF / Engineer Foundation Conference held in 1993.
