摘要
Abstract
The measurement and analysis results of void fraction waves in different flow regimes show that the propagating velocity of void fraction wave depends on flow regimes and mean void fraction. The disturbance at some frequencies can enhance the velocities of phase and void fraction waves. The non-linear analysis indicates that the instability of bubbly flow is a chaotic process. Before the bubbly flow transits to cap-bubbly flow, the growth rate of void fraction wave becomes the maximum value when the disturbance frequency is close to the main frequency of void fraction wave.关键词
