The Boundary Integral Method (BIM) is widely used to simulate nonspherical bubble dynamic behaviors due to its high accuracy and efficiency. However, conventional BIM cannot simulate toroidal …
WebMar 8, 2024 · The researchers created a model for predicting the velocity and height of jet aerosols produced by bubbles from 20 microns to several millimeters in size, and in liquids as viscous as water, or up to ten times more viscous. The “jet” refers to the liquid that spurts up after a bubble has burst.
WebAt the same time, two opposing jets are produced pointing to the opposite plate. The jet passes through the sub-bubbles and vortexes form in the center of the bubbles. The vortex attracts the edges of bubbles converge into the central, forming distinctly bevel.
