Abstract: Drilling bits which exploit the destructive energy of cavitation are being developed. A systematic series of tests is now under way, first to establish feasibility, and then to define the ...

Abstract: The erosion and cleaning effect of jets is enhanced when the degree of cavitation on or near the bottom of the hole is increased. Analyses indicate that self-excited, acoustically resonating ...

Abstract: Analyses of self-excited, resonating jets have been corroborated by laboratory experiments. These structured jets achieved cavitation at greater ambient pressures and showed enhanced erosivity in ...
