| Abstract: | It is shown experimentally that the unbounded bubble cavitation in a highly viscous liquid (glycerin) can develop only in
a regime of very slow volume tension of a liquid sample. Upon pulse volume tension, cavitation in the sample damps at the
initial stage (the bubbles do not reach pronounced sizes) and fragmentation occurs because of perturbations generated on its
free surface. The mechanism of bubble growth from micropores in a thixotropic medium (gel) is explained based on experimental
results and theoretical estimates.
