Application of high-resolution gamma ray tomography to the measurement of gas hold-up distributions in a stirred chemical reactor

We employed high-resolution gamma ray tomography to measure radial and axial phase distributions in a laboratory type chemical reactor with a gas-inducing turbine stirrer. Therefore, we employed a recently developed gamma ray CT system which uses a Cs-137 source and a detector that achieves approximately 2 mm spatial resolution. The measured data has been compared to computational fluid dynamics predictions obtained with CFX 10.0.
