← ScienceWhich energy loss increases alongside sustained cavitation in ultrasonic cleaning transducers?
A)Increased frictional damping
B)Elevated thermal generation✓
C)Reduced piezoelectric efficiency
D)Suppressed magnetic hysteresis
💡 Explanation
Increased cavitation intensity raises vibration beyond material limits causing energy dissipation as heat stress; this occurs because of increased thermal generation due to the violent bubble collapses, therefore raising heat, rather than damping or hysteresis which would predominate under controlled operation.
