Abstract
- The evolution of the particle‑induced hemispherical bubble bursting process is invistigated using high‑speed camera filming. The edge regeneration and convection after bubble formation, the probability of bubble bursting when subjected to particle penetration, and the bubble bursting behavior after hole formation are observed and analyzed. Through dimensional analysis and experimental research, it is found that the probability of bubble breaking probability is a function of Reynolds number and Weber number. The probability is given by P = 1. 08 (Re0. 5We0. 25)0. 664, and the probability is reaches to 100% when Re0. 5We0. 25>1 020. The number of ligaments formed by bubble bursting is a function of the Oh number. The rim receding velocity of the bubble liquid film increases with the concentration of the solution increases and the film thickness decreases with the concentration increases.
