In this experiment, three experimental conditions are selected for testing (see Methods for more details). a Flow profiles captured by the camera. At the initial stage of the experiment, the pipe is filled with liquid (see (i)). The gas and liquid flow into the testing section with volume flow rates of 20.0 and 5.0 m3/h, respectively. The gas-liquid two-phase flow with high liquid volumetric concentration is then formed (see (ii)). When the volume flow rate of the gas rises to 100.0 m3/h and that of the liquid drops to 2.5 m3/h, the gas-liquid flow with low liquid volumetric concentration is formed (see (iii)). b Tomographic images obtained from our Digital Twin (DT) framework. (iv) Tomographic images and liquid volumetric concentration variations of the gas-liquid flows in a. Tomographic images in (v) and (vi) show two sets of representative images selected from the time-stacked cross-sectional reconstruction results in (iv).
