Numerical calculation of the shear stress generated by the flow field induced by an oscillating bubble between two solid boundaries Conference Paper uri icon


  • The purpose of this study is to calculate the shear stress that is produced on a surface due to the flow field induced by an oscillating cavitation bubble generated with a continuous wave (CW) laser in a saturated copper nitrate solution using COMSOL software. The calculation is based on experimental results of a previous report where cavitation bubble dynamics using high speed photography of CW laser-induced bubbles with a time resolution of 7 μs per frame was studied. The shear stresses originated within the flow field around the oscillating bubbles have been calculated to have a maximum value of 9500 Pa. © 2012 Springer Science%2bBusiness Media New York.
