TL;DR: A novel attempt to capture, identify and predict the individual flow regimes for different combinations of air and water superficial velocities based on some of its objective descriptions, with GA-MLRBFNN-EC being the best to predict flow regimes successfully.

TL;DR: In this article, an improved flooding correlation is proposed which accurately correlates the data of three previous investigations, and the results clearly show that some flooding data had been misinterpreted in the past.

TL;DR: In this paper, a constant electric current method (CECM) is proposed for conductance measurement. But the performance of the CECM is limited due to the fact that the output from the sensor electrode is independent of the location of gas phase, and the sensitivity of detecting the change in the hold-up is higher in the case of thinner film thickness.

TL;DR: The gas velocities for flooding in a wetted wall column have been measured as a function of liquid viscosity and flow rate as mentioned in this paper, and they were found to be somewhat higher than those predicted by D avidson and S hearer.
