(141c) Advanced Non-Invasive Radioactive Particle Tracking (RPT) and Dual-Sources Gamma Ray Computed Tomography (CT) Techniques for 3D Hydrodynamics Measurement for Multiphase Flow Systems (Visualization and Quantification)

Multiphase flow systems are extensively used in chemical and biochemical industries. Where perfect mixing and ideal mass and heat transfer are crucial for high efficient operations. Because the local flow dynamics parameters are the main factor for multiphase systems effective reactor design and successful scale-up. Consequently, these parameters require a suitable understanding through the reactor running stages. Unfortunately, these parameters need to be further developed and evaluated to account of the flow dynamics field in each location inside the reactor which is unclear yet and need more information for deeply understanding. Therefore, in this work, 3D local hydrodynamics have been measured extensively for different multiphase flow systems such as, bubble/slurry bubble (lab and pilot plant scales) with and without heat exchanging tubes, biochemical (cylindrical photobioreactor), spouted bed (different scales), fluidized bed (lab and pilot plant scales), and trickle bed columns by using a non-invasive advanced radioactive particle tracking (RPT) (for lab and pilot scales) and dual-sources gamma-ray computed tomography (CT) techniques. In our laboratory (Multiphase Flow Reactors and Applications Laboratory MFReal), the diagnostics techniques have been well established and used extensively for monitoring the flow field in a non-invasive manner in opaque multiphase reactor systems. The experimental results and conclusions will present at the conference.
