WebHowever, how a structurally complex interface, widely present in nature, mediates the bursting process remains largely unknown. Here, we document the bubble-bursting jet dynamics at an oil-covered aqueous surface, which typifies the sea surface microlayer as well as an oil spill on the ocean. The bubble bursting dynamics at an oil-covered aqueous surface is observed by two synchronized high-speed cameras from side views above and below the liquid surface (Fig. 1a). No surface-active material is added in any liquid. The gas bubble approaches the oil-covered aqueous surface after being released. Then the … See more In our experimental system, after the simultaneous rupture of the oil and water films on the bubble cap, the cavity collapses, with capillary waves propagating … See more While Bo compares the gravity and capillary effects, Oh compares the viscous damping rate of the cavity collapse, ${t}_{{{{{{\mathrm{d}}}}}}}^{-1}$, and the inverse of the time of … See more Here we show that the formation of oily jets results from the spreading of oils along the surface of the collapsing cavity. For the bubble … See more We further investigate how the oil spreading at the cavity surface modifies the jet dynamics. It has been stated that the capillary wave propagation during cavity collapse plays an important role in the jet dynamics … See more
