Abstract: | Comprehensive numerical and experimental analyses of the effect of
viscosity on cavitation oscillations are performed. This numerical
approach is based on the Rayleigh--Plesset equation. The model
predictions are compared with experimental results obtained by using
a fibre-optic diagnostic technique based on optical beam deflection
(OBD). The maximum and minimum bubble radii as well as the
oscillation times for each oscillation cycle are determined according
to the characteristic signals. It is observed that the increasing of
viscosity decreases the maximum bubble radii but increases the
minimum bubble radii and the oscillation time. These experimental
results are consistent with numerical results. |
