Simulation of Rayleigh Bubble Growth near a No-Slip Rigid Wall

In order to study the role of growing cavitation bubbles in context ultrasonic cleaning, we perform two-dimensional, axisymmetric Navier-Stokes simulation for compressible, multicomponent flow and examine so-called Rayleigh growth an air bubble (with initial radius 33 µm pressure 10 MPa) near a rigid wall. The suggests that strong shear stress, which is important physical cleaning such as particle removal, appears result bubble-growth-induced shock passage. parametric with varying standoff distance wall shows stress linearly decreases against distance.
