±à¼Óʼþ¸øµÄÉó¸åÒâ¼ûÈçÏ£º Comments from the editors and reviewers: -Reviewer 2 - The paper describes an interesting in-situ (laboratory) method that can be used to assess the cavitation potential of a turbine's blade tip. It does this by combining acoustic data recorded from a microphone with pressure/optical data. The acoustic method used falls within the passive techniques used extensively in the detection and characterization of cavitation. Although the authors have put a great deal of effort into their work and it is well documented, there are several issues that must be addressed before publication: 1. Present a more detailed mathematical apparatus linking cavitation properties (pressure, fluid velocities, water temperature, nuclei density, etc.) to signal parameters (time, frequency, spectra, statistics, etc.). 2. Little is being said about the spectral content of recorded signal. What males a "pulse" different from a "collapse" (a zoomed detail would be welcomed)? 3. What happens to the signal for different values of the velocity? 4. Noise analysis: as the signal recorded is in the audible range, a noise analysis would be welcomed to assess the method's overall robustness. 5. The overall aspect of the paper: figure 1: a more detailed picture about the hydrofoil and microphone positioning would be welcomed. 6.How does the temperature influence the results of the test (especially the cavitation number)? 7. What is the velocity range for which cavitation inception occurs? Can you trace the The reason for which a major review is required relies on the reason that a clear acoustic criterion for cavitation inception metric cannot be seen yet in the paper.
