Abstract: | We have been using the method of tube-arrest as a means of producing
transient single cavitation bubble. In the present paper we seek to
comprehend the mechanism of production and inquire into the structure
of the {\em ab initio} pressure field in the arrested liquid column.
The generated pressure wave is shown by combining the theoretical
analysis with the experimental observation to be a slightly varied
version of water hammer. With relatively clean liquid, the magnitude
of the tension peak generating the TSB is likely to reach of several
millions Pa. It is also shown that the so generated cavitation bubble
originating from the gas-containing bulk liquid is in `violent'
motion. |
