Abstract
The slug flow pattern has a liquid and gas intermittence characteristic and, this pattern is found especially in oil and gas production and transportation lines. The slug flow behavior is important for the correct industrials equipment design those operates in the lines. In deep-water oil operations, it is common to observe situations where the piping needs to adjust to the seabed relief, thus causing direction changes in the flow. In this context, the present work presents a liquid-gas two-phase slug flow pattern experimental study in ducts with slight direction changes, consisting of initial horizontal stretches followed by an upward inclined stretch with angles of + 3 °, + 5 ° and + 7 ° with respect to the horizontal in a 26-mm ID, 35,7-m long pipe. Resistive sensors were installed at four different locations to measure the slug flow characteristic parameters. Based on the obtained results, the slight direction change influence was evaluated in the characteristic parameters changes.
