6 However, it seems little attention has been paid to them these days. 2 Nuclei in hydraulic mineral oil In this book, hydraulic oils for fluid power machines are used as primary test liquids to observe cavitation. Considering that an overwhelming majority of cavitation studies have been conducted in water flows so far, oils may be unfamiliar liquids to most cavitation researchers. However, the use of oil has its own merits which the readers will soon understand as they go on reading. First of all it will help make the unsoundness of nuclei models clearer, so we will start this section with a discussion about nuclei in hydraulic mineral oils.

5], the term of pressure difference pG – pL represents an outward force to expand a bubble, whereas that of surface tension 2φ/λ shows an inward one to contract it. When the tension exceeds |pLmin|, the former becomes larger than the latter, which will cause an explosive growth of the bubble as well as a drop of pressure to absolute zero. It should also be pointed out that even if the oil pressure pL is lowered to pLmin, pG remains positive (pG = −pLmin/2 > 0). Calculating tensile strengths of bubbles by Eq.

11] The absolute value of pLmin corresponds to a maximum tension an oil containing a spherical bubble can endure. Then what happens when we apply a tension larger than |pLmin| to the oil? If we do, the equilibrium of forces Eq. 5] 24 Review of cavitation nuclei no more holds true and consequently the bubble behavior cannot be predicted by Eq. 7]. In Eq. 5], the term of pressure difference pG – pL represents an outward force to expand a bubble, whereas that of surface tension 2φ/λ shows an inward one to contract it.
