The bubble eruption process was studied in two‐ and three‐dimensional (2D and 3D) beds using a high‐speed video system for flow visualization. The results show the existence of four different ejection mechanisms; one occurring with singlebubble eruptions in both 2D and 3D beds, two others occurring in 2D and 3D beds with two bubbles coalescing at the bed‐free surface, and the fourth occurring only in 3D beds with bubbles coalescing at the bed surface.
