Flow distribution of gas and liquid in parallel pipes

Prediction of two‐phase flow distribution in parallel pipes using stability analysis

“…For further increase of the flow rates, two phase flow is observed in three pipes, and finally for higher flow rates, the flow takes place in all four pipes. 16 The main objective of the present work is to predict the flow distribution and compare it with the experimental results. Figure 2 shows such a system.…”

“…Taitel et al 16 investigated experimentally the distribution of gas and liquid in four parallel pipes with a common manifold. They found an interesting phenomenon, that under certain conditions the two phases "choose" to flow only in 1, 2, 3 or 4 pipes (out of 4), while stagnant liquid columns are observed in the other pipes.…”

Two-phase flow pressure drop hysteresis in parallel channels of a proton exchange membrane fuel cell

“…This complexity includes large gas to liquid ratios, water produced by electrochemical reaction entering the flow field channels from a porous wall (GDL), and water entering the flow field channels from the condensation of humidified gas reactants. Water introduction from the porous GDL is different from traditional two-phase flow studies [4][5][6][7], where the two phases are typically introduced together or mixed before the inlet. This difference makes two-phase flow studies in fuel cell flow channels particularly unique.…”

Multiphase Flow Splitting in Parallel/Looped Pipelines

“…These include Hwang et al (1989), Hong and Griston (1995), and El-Shaboury et al (2007). Taitel et al (2003) investigated the splitting of gas-liquid two phases in 4 parallel pipelines with common inlet and outlet manifolds, capable of rotating between 0-15 degrees.
