Flow Frictional Characteristics of Air–Water Flow Characteristics under Stable and Transverse Vibration Conditions in Horizontal Channels

We experimentally studied the air–water pressure drop characteristics with inner diameters of 20 mm under stable and transverse vibration conditions in horizontal circular channel. experimented status gas-phase conversion flow velocity Jg at 0.1–20 m/s, liquid-phase Jw 0.1–3.0 m/s. In this paper, we discuss effect velocity, amplitude, frequency on drops. With increasing performance drops become more intense. Thus, frictional increases. Moreover, increases linearly velocity. compared experimental results calculated previous empirical correlations. Based Chisholm-C correlation, obtained a modified correlation for factor C channels conditions. The new considers channel confinement number, frequency, vapor quality. has relatively good prediction experiments, mean absolute deviation is 8.2%.
