... the process of inception, development, and saturated condition of cavitation phenomenon in injector nozzle. Second, the inner-nozzle flow characteristics are more sensitive to small diameter than large diameter under the short nozzle length, while the sensitivity of the inner-nozzle flow characteristics...

...Maria Grazia De Giorgi; Daniela Bello; Antonio Ficarella The cavitation phenomenon interests a wide range of machines, from internal combustion engines to turbines and pumps of all sizes. It affects negatively the hydraulic machines’ performance and may cause materials’ erosion. The cavitation...

.... Focusing on the effect of microcavitation on the vortex structure, we compared the Q profiles in the case with and that without the cavitation model as shown in Figs. 11 12 . The diameter of each vertical vortex in the microcavity generated region was found to become smaller than that in the case...

... on the modeling of dynamic film rupture. Usually, the cavitation models developed for journal bearings are applied to SFDs. Yet, the characteristic motion of the SFD results in the entrapment of air into the oil film, producing a bubbly mixture that cannot be represented by these models. There is a need...
