Cavitation microstreaming reveals two distinct flow physics based on frequency of acoustic excitation, impacting lab applications.
At low frequencies, vibration-induced flow dominates streaming patterns, altering bubble behavior significantly.
Using the Energy Minimization Method, the study verifies bubble shapes under confinement, which influences flow regimes.
Micro-PIV analysis illustrated the velocity field of the bubbles, providing crucial data for optimizing sonoporation and micro-mixing experiments.
