... diameter downward inclined pipeline (-15 and -30°) have been used. Superficial liquid and gas velocities are varied from 0.1 to 1.6 m/s and 1 to 7 m/s, respectively. In addition, the experimental results are compared to the predictions of existing mechanistic models for pressure gradient, liquid holdup...

..., even though all the risers are operated using gas lift. The cases were simulated using LedaFlow versions 2.6 and 2.7, and the results showed that the pressure drop predictions obtained using LedaFlow 2.7 were significantly more accurate than with LedaFlow 2.6. The most pertinent difference between...

Paper Number: ISAVFT-2023-011
... In this paper we compare predictions obtained using the LedaFlow Slug Capturing model with a new and unique set of slug flow experiments. The most important novelty of these experiments is that they were conducted in a very long pipe (766 meters), so that slug length evolution could be studied...

Paper Number: ISAVFT-2023-449
... Accurate prediction of flow patterns for two-phase flows in pipes is vital for optimum design and flow assurance of production systems. Currently, mechanistic models are widely used to predict flow patterns in pipes at different operational, geometrical, and fluid properties conditions. However...
