Subharmonics are not an infallible safety metric for cavitation dynamics

Key Points

• The research aims to evaluate the reliability of subharmonic signals as safety indicators in cavitation dynamics.
• Analyzed the presence and absence of subharmonic signals in relation to cavitation events.
• Evaluated safety implications of using subharmonics as metrics in various applications.
• Assessed scenarios where off-target cavitation could pose safety concerns.
• Subharmonic signals are not always reliable indicators of cavitation.
• Presence of subharmonics does not guarantee safe cavitation dynamics.
• Caution is advised in relying solely on subharmonics for assessing safety in cavitation applications.
