THE MORK FAMILY DEPARTMENT OF CHEMICAL ENGINEERING AND MATERIALS SCIENCE PRESENTS A SEMINAR BY

Dr. Hugh StittJohnson Matthey"What flow visualisation can teach us about reactor
design (What? Flow visualisation can teach us about
reactor design?)"Abstract:
Reactor design in industry is still dominated by empirical methods and the use of design
margins. Flow visualisation techniques such as tomography and velocimetry are extensively
used as research tool for, especially multiphase, reactors. While the images and movies can
be impressive, they do not in themselve give us quantitative guidance in reactor design. How
should and can we use these to improve reactor design in practice? The use of these
techniques to improve uderstanding of reactor hydrodynamics and their use to underpin and
validate phenomenological models that can potentially used in design will be briefly
reviwed. The question then is how can these techniques benefit scale up, design and
operation of commercial reactors. Examples will be presented of using flow visualisation in
scale up studies and in diagnostic studies of commercial reactors, and the different demands
of flow visualisation in lab, pilot and commercial reactors discussed.Thursday, November 17, 2005
