Abstract
<jats:p>Investigations about the role of nuclei and nucleation for the inception and formation of cavitation have been part of cavitation research since Harvey <jats:italic>et al.</jats:italic> (<jats:italic>J. Cell. Physiol.</jats:italic>, vol. 24 (1), 1944, pp. 1–22) postulated the existence of gas filled crevices on surfaces and particles in liquids. In a supersaturated liquid, surface nuclei produce small gas bubbles due to mass transfer of gas or themselves work as weak spots in the liquid that are necessary for a phase change under technically relevant static pressures. Although various theories and models about nuclei and nucleation have found their way i...
