摘要：

The sound speed in the shear layer in the oscillation chamber and effects of gas content in fluid on oscillating frequencies of self-excited oscillation water jets were investigated. It was shown that the oscillating frequencies of water jets, which directly influence the cavitation intensity and erosive ability of water jets are related to the chamber structure and water jet parameters. The sound speed in the oscillation chamber has different characteristics from the single phase flow, hence would influence the oscillating frequencies. It was demonstrated that the penetration rates and the footages of the bits have been increased by up to 50% and 15%, respectively, over the rates for similar bits with conventional jet nozzles.
