Different snapshots graph

There is only one version of the flowsheet in Fig. 3.72. Here, we rely on the capabilities of the flowsheet editor to represent multiple variants. Still, the flowsheet could evolve into multiple versions at the managerial level (e.g., to record snapshots at different times). Moreover, in the case of a flowsheet editor with more limited capabilities (no variants), variants would be represented at the managerial level as parallel branches in the version graph. 

By examining the snapshots from the simulations, we noticed that the bubbles inside the membrane arrays exhibit a different shape compared to bubbles in a bed without inserts. The bubbles are often connected via membrane tubes or connected to the additional void underneath each membrane tube. Moreover, bubbles inside membrane arrays seem more irregularly shaped compared to the situation without inserts. To obtain a better insight in this phenomenon, the perimeter of each bubble was calculated by DIA, and the results are plotted as a function of the bubble size in Fig. 4.55. These graphs confirmed our visual observation in almost all cases, the bubble perimeter of systems with membrane arrays (inline and staggered) exceeds the perimeter of the wall simulations above a bubble diameter of approximately 30 mm. Only for the 100% —40% series (Fig. 4.55A), the bubbles did not reach a certain bubble size to allow a conclusion to be drawn...
