Understanding pharmaceutical flows

The combined use of experimental fluid dynamics (EFD) and computational fluid dynamics (CFD) methods effectively identifies and addresses flow problems in the pharmaceutical industry. Process performance and reliability can be improved with the application of this technology. This article demonstrates the use of EFD/CFD with diverse examples, including a laboratory dissolution apparatus, stirred tanks in various configurations, mixing of non-Newtonian fluids, static mixers, and roller bottles. Flow patterns, mixing structures, and complex behavior are all revealed with the combination of EFD and CFD methods.
