... and a Strouhal number. Secondly, a theoretical analysis of fluid-structure interaction yields a screening expression of the structure velocity power spectral density (PSD), as a function of the acoustic pressure source. Field data are used for validation. It is shown that cavitation-induced vibration can...

...Jun Ishimoto; Masahiro Onishi; Kenjiro Kamijo The thermodynamic effect on cryogenic cavitating flow characteristics of pressurized liquid nitrogen in a horizontal rectangular nozzle is precisely investigated by numerical analysis based on an unsteady thermal nonequilibrium two-fluid model...

... generation of a heat-affected zone (HAZ), severe plastic deformation, crack blunting, cavitation, fracture initiation, and generation of residual stresses. In addition, several of the deformation effects observed in the HAZ indicate superplasticity. The results are compared with data from surfaces exposed...

.... It was revealed from the experimental results that creep damage mechanism of a welded joint was mainly creep cavitation, and that the intensively damaged area by creep cavitations was the transition region from fine-grained heat-affected zone (HAZ) to unaffected base metal, namely intercritical HAZ. For both...
