WebDec 1, 1970 · This paper is a review of existing knowledge on cavitation nuclei. The lack of significant tensions in ordinary liquids is due to so-called weak spots or cavitation nuclei. The various forms which have been proposed for nuclei are gas bubbles, gas in a crevice, gas bubble with organic skin, and a hydrophobic solid. The stability argument leading to …

WebApr 1, 2009 · Harvey nuclei have been suggested as the source of bubble formation in many physical and biological systems ( Ryan and Hemmingsen, 1998 ). In terms of flotation, Harvey nuclei would be mainly related to naturally hydrophobic minerals such as coal.
