This research developed an experimental method for validating the CFD representation of single phase (vapor) flow through structured packing. Real time X-ray radiography was used to visualize fluid streamlines in structured packing by tracking neutrally buoyant X-ray absorbing particles entrained in water flow. Flow through the packing was found to be uniform while flow at the packing element joints exhibited chaotic flow and recirculation zones. Individual radiographs were analyzed to determine particle displacement and compute local velocities.
