... methods were tested on simulated data which was generated by a multiphase flow simulator. The results showed that these methods are accurate in monitoring both flow rates and slugging characteristics (amplitude and frequency). Additional insights via PCA-based visualizations show that slugs could...

The results of the measurements are compared to theory of waves and turbulence. production monitoring wavelength trough crest coordinate system case 1 amplitude axial velocity liquid layer...

... in the water phase. The addition of the polymer extended the region of stratified flow and delayed the transition to dual continuous and dispersed flows. It also resulted in a decrease of interfacial waves, increase in interfacial wavelength, and decrease in wave amplitude. The polymer also reduced...

... (gas/liquid) flow. A novel all digital Coriolis mass flow transmitter with sophisticated amplitude control has been developed. It can operate not only in bubble but also in slug flows. The paper presented some air water and air oil results and comparison was made with the theory. The theory agreed...

... surface tension and predicted critical wave amplitude that leads to entrainment for a specific wavelength. Experimentally wave characteristics before and at the onset of entrainment were investigated by measuring the instantaneous fluctuation of the interface between oil (6mPas, 828kg/m 3 ) and water...
