 note = {Flow of bubbly liquid in divergent-convergent nozzle is investigated numerically. First a steady flow is obtained and then small pressure fluctuations are imposed on the flow at the nozzle inlet. It is found that the voidage waves are induced by the applied pressure fluctuations. They propagate downstream through the nozzle with the same velocity as that of the bubbles. Theoretically, voidage waves are expected to be amplified and the flow becomes unstable in the throat region where the velocity slip between the liquid and the gas bubbles is present. Numerically, however, the unstable behavior of the voidage wave was not found at least in the present numerical simulations. This might come from the fact that the artificial viscosity involved in the numerical scheme tends to suppress the amplification of unstable waves., 資料番号: NALSP0014023, レポート番号: NAL SP-14},
