We study systematically the cavitation-induced wall shear stress on rigid boundaries as a function of liquid viscosity and stand-off distance using axisymmetric volume of fluid (VoF) simulations. Here, is defined with the initial distance of bubble centre from the wall and the bubble equivalent radi...
