Flow Visualization in Fluidized Bed Reactor
An integrated workstation for the study of fluid and particle motion in a fluidized bed reactor, which will permit effective and safe drug removal within an extracorporeal system, was constructed. Our main objective was to identify and investigate those flow conditions which will yield high efficiencies of heparin removal and low levels of blood damage. This workstation, which can be used as a general purpose fluid and particle motion analyzer, enabled the investigation of the complex dependence of the overall reactor performance on flow conditions at a micro-level. The workstation·s main features include real-time capture and analysis of video-information, a user-friendly interface, graphics displaying various time-dependent flow parameters, and image processing features for selecting the area and image contrast for visualization.
