文摘
- •
Cavitation in sulphuric acid with spatially separated sonoluminescence emission colours.
- •
High-speed imaging reveals different cavitation bubble populations in the differently coloured zones.
- •
“Blue” bubbles are slow and collapse spherically, “red” bubbles move fast and show liquid jetting during collapse.
- •
Findings support liquid injection by jetting as promoter of sodium sonoluminescence.
- •
Numerical modelling of bistable bubble dynamics.
