Abstract: | The characteristics of turbulent bubbly regime of gas and liquid flow in a horizontally oriented large pipeline have been presented. Various techniques such as hot film anemometer, Pitot tube, miniature pressure transducers and orifice meters were successfully employed to measure the two-phase flow parameters, void fraction, mixture velocity and wall pressure fluctuations.
Different semi-empirical correlations have been developed for predicting the turbulent characteristics in radial and axial directions in terms of the volumetric flow ratio. Spectral analysis was performed to study the turbulent flow fluctuations and their distributions over different wave numbers. Finally, the fully developed flow has been analytically and spectrally studied. |
