AI Technical Summary

Problems solved by technology

However, the oscillation inside the self-excited oscillating nozzle is unstable, and the jet pulse characteristics are poor, and because the internal line shape of the self-excited oscillating nozzle usually has a sudden change in section, it will cause a large fluid energy loss, which is not conducive to impact crushing
