Dataset

The thesis related to this dataset investigates, for the first time, the tomography-based real-time control of multiphase flows. A gas-liquid axial cyclone separator is used in the experiments, that combine (i) the development of fast tomography algorithms for real-time control applications, (ii) the physics of swirling gas-liquid flows, (iii) the phase distribution dynamics in the axial cyclone, and (iv) the tomography-based real-time control of the phase distribution near the cyclone outlets. This dataset contains experimental data related to: (i) the real-time Electrical Resistance Tomography (ERT) image reconstruction algorithm proposed in the current research to measure cyclone flows in the columnar regime, resulting in phase distribution reconstructions more precise and up to three orders of magnitude faster than traditional ERT algorithms ( Chapter 2 of the thesis); (ii) flow pattern maps of the vertical upward swirling gas-liquid pipe-flow patterns that can be created in axial cyclones for a wide range of gas and liquid flow rates and different swirl intensities, presented and modelled in Chapter 3; (iii) time-average efficiency and time-average phase distribution near the cyclone outlets, used to investigate if the separation can be described as a one variable function of the time-average gas core diameter in Chapter 4; (iv) measurements of the gas core in different locations of the axial cyclone, used to study the relation between the phase distribution dynamics in the axial cyclone and in the upstream flow, and the gas core response to actions in the control valve in the cyclone outlet. The phase distribution response to the valve is used to design a real-time controller to suppress external disturbances in the phase distribution, and the obtained results are also included in the dataset (Chapter 5). The experiments were performed using cameras and ERT to record the phase distribution, and the processed results presented in the thesis are uploaded in the excel tables of the current dataset.
