“…The interaction between bubbles and inclusions had been studied for long time and many references. [9][10][11] Two main ways of interaction between bubbles and inclusions were acceptable, which also were supported by our present study. (1) Small inclusions followed the bubbles' moving track in their wake; as shown in Fig.…”

The distribution and detriment of bubbles in ultra low carbon interstitial free steel were studied by X-ray radiographic and cold-rolled experiment; a total of 24 pieces samples with size 230 mm × 65 mm × 2 mm were detection and 150 bubbles were counted; the results showed that: (1) Two bubbles bands formed in continuous casing slab; bubbles distributed asymmetrically in thickness direction of the slab; small bubbles mainly concentrated in inner art side 1/8 to 1/4 in thickness direction; large bubbles were main in center of the slab in thickness direction; (2) Hundreds of inclusions with sizes 2 μm to 10 μm accumulated in cone-shape region after bubbles. Inclusions or Fe and FeO particles often attached or mixed with the bubbles. (3) Small bubbles entered into down-flow easily and rushed out the mould, bubbles and inclusions accumulative band formed in inner art side of the slab. (4) The bubbles, inclusions around the bubbles or large Fe and FeO particles mixing with bubbles became source of the sliver defect.

“…Many researchers, e.g. [14][15][16] investigated the interactions between flow and many bubbles in the context of bubble-column reactors, bioreactors, etc. However, in line with the context of the present study, we only review the previous investigations conducted on a pair of bubbles rising side by side.…”

Two initially spherical bubbles rising in quiescent liquid

et al. 2017

A pair of bubbles starting from rest and rising side-by-side in a liquid have been shown earlier to display spherical and ellipsoidal shapes. In contrast to earlier computational studies on the two-dimensional dynamics of a pair of bubbles, we study the fully three-dimensional motion of the bubbles in the inertial regime. We reveal the destabilizing nature of the interaction between the wakes of the bubbles, which causes them to rise in an oscillatory path. Such three dimensionality sets in earlier in time than for a single bubble and also at a lower inertia. The interaction leads to a mirror symmetry in the trajectories of the two bubbles, which persists for some time even in the high inertia regime where each path is chaotic. The e↵ect of the inertia and initial separation on the mirror symmetry of the path, the vortex shedding pattern and the attraction/repulsion between the bubbles are examined. The bubble rise has been interestingly observed to be symmetrical about the plane perpendicular to the separation vector for all separation distances considered in the present study.

“…A remarkable set of papers 5,6,[13][14][15] study bubbly flows in which the interaction between the flow and a large number of bubbles is studied. In particular, turbulent flows can be significantly affected by bubbliness.…”
