Predicting the onset of cavitation, i.e., the generation of gas cavities in liquids and solids subjected to negative pressures, is critical to a variety of biomedical ultrasound, naval hydrodynamics, and ultrasonic cleaning applications. While the homogeneous cavitation threshold is an important intrinsic material property, measurements of acoustic cavitation thresholds in water differ from those predicted by classical nucleation theory. This discrepancy may be explained by the presence of nanometer-size heterogeneous nuclei, which may themselves be an intrinsic material property.
