Key Benefits Include: identify regional changes in process conditions over time for comparison with CFD predictions provide process information to improve CFD models determine repeatability of process conditions to characterise inherent process variability Process Tomography Solution: Process tomography provides concentration measurements through a process volume. This data can be used to test and validate CFD models. In applying tomography to CFD challenges, a key aspect is the accuracy of the tomography data and the confidence levels in the CFD model. Process tomography can be used to test and validate a wide range of CFD models, including: gas-liquid mixing solid-liquid mixing multi-phase flow packed bed reactors Typically our p2000 instrument is used for cold models where water is used as a surrogate material. Depending on the nature of the process, a variety of different reconstruction methods can be used, including SCG (Sensitivity Conjugate Gradients) and parametric reconstruction.
