“…This observed effect of x 1 is consistent with the case of stratified flow (seen in Figs. 5 and 6) and also consistent with the observation made by Ottens et al [7] and El-Shaboury [22] for the same flow regimes.…”

“…As mentioned above, there are more studies on equal gas-liquid ratio distributions in the literature than on equivalent flow distributions. El-Shaboury et al [12,13] summarized the literature on gas-liquid twophase shunt characteristics at impact T-tubes and discussed in detail the influence of the inlet gas surface velocity, liquid surface velocity, mass and pressure. A new parameter, the momentum flux ratio, is proposed to explain the shunt behavior of the GLTPF.…”

When a gas-liquid two-phase flow (GLTPF) enters a parallel separator through a T-junction, it generally splits unevenly. This phenomenon can seriously affect the operation efficiency and safety of the equipment located downstream. In order to investigate these aspects and, more specifically, the so-called bias phenomenon (all gas and liquid flowing to one pipe, while the other pipe is a liquid column that fluctuates up and down), laboratory experiments were carried out by using a T-junction connected to two parallel vertical pipes. Moreover, a GLTPF prediction model based on the principle of minimum potential energy was introduced. The research results indicate that this model can accurately predict the GLTPF state in parallel risers. The boundary of the slug flow and the churn flow in the opposite pipe can be predicted. Overall, according to the results, the pressure drop curves of the two-phase flow in the parallel risers are basically the same when there is no bias phenomenon, but the pressure drop in the parallel riser displays a large deviation when there is a slug flow-churn flow. Only when the parallel riser is in a state of asymmetric flow and one of the risers produces churn flow, the two-phase flow is prone to produce the bias phenomenon.

“…They concluded that these devices have a significant influence on the phase split. El-Shaboury et al [11,12] summarized the literature on the gas-liquid two-phase flow split characteristics at the impacting T-junction, and discussed in detail the effects of gas velocity, liquid velocity, mass and pressure at the inlet. A new parameter, momentum flux ratio, was proposed to explain the splitting behavior of gas-liquid two-phase flow.…”

Dedicated experiments and numerical simulations have been conducted to investigate the splitting characteristics of a gas-liquid two phase flow at a T junction. The experiments were carried out for different gas-liquid velocities. The flow rates in the two branches were measured accurately to determine how the two considered phases distribute in the two outlets. The experimental results have shown that when the two outlet pressures are asymmetric, the two-phase flow always tends to flow into the outlet which has a lower pressure. As the inlet liquid velocity increases, however, the two-phase flow gradually tends to split evenly. Compared with the experiment results, the pressure difference between the two outlets can be determined more accurately by means of numerical simulation. The trends of experimental results and simulations are in very good agreement.
