| Abstract: | Numerical simulation of bubble rising in reduced pressure vessel was carried out by volume of fluid method (VOF) solver of OpenFOAM, open source CFD toolkit. The result was validated against the experimental data of Kumagai et al. [Tetsu-to-Hagané, 101(2015), 93]. Behaviors of continuous rising bubble at 101.3 kPa, 18.2 kPa, 4.5 kPa were almost consistent with the experiment. The shape of bubble near injection nozzle at 101.3 kPa was more ellipsoidal than that of experiment and the mesh refining decreased the difference. Single bubble rising behavior was also studied. Rising rate and outside appearance were almost consistent, but slight continuous dispersion of gas phase from tail end of bubble was observed in only simulation and it was considered the issue of gas-liquid interface modeling. The cross section of bubble was spherical cap and consistent with the diagram of Grace [Trans. Inst. Chem. Eng., 51(1973), 116] |
