“…The Ž . model of Shoham et al 1987Shoham et al , 1989 is an example of the so-called geometrical models valid for annular and stratified-wavy flow. The flow split in this model is to a large extent governed by a virtual vertical split line through the inlet, dividing both the gas and liquid between the branch and the run.…”

“…For decades, researchers have been trying to explore the effects of T-junction geometry by conducting experiments on regular and reduced diameter ratio T-junctions [8,9]. On the other hand many researchers have tried to dig out the effects of flow regimes such as stratified, stratified wavy, slug and annular flow on phase separation in a T-junction [10][11][12][13]. From these studies, it was found that better phase separation is achieved in stratified flow as compared to annular and slug flow.…”

The utilization of T‐junctions for flow division is quite common in industries. Due to the phenomena known as multiphase maldistribution, occurring in a T‐junction, they are often used as partial phase separators for reducing the work load on phase separation devices in oil and gas platforms. Previous literature says that reducing the diameter ratio of the T‐junction improves the two‐phase separation, however it was also reported that reducing the diameter ratio too much has a negative effect on two‐phase separation. To test this, a numerical study was performed to see the two‐phase stratified flow separation in 1, 0.6 and 0.167 diameter ratio T‐junctions. Furthermore, the impact of air superficial velocity on phase maldistribution at the junction is also considered. The T‐junctions with diameter ratios 1 and 0.6 were just used for the validation of present model, by comparing the obtained numerical results with previous experimental data. While, 0.167 diameter ratio T‐junction is the one for which the actual analysis was performed. It is concluded that an increase in air superficial velocity aids liquid carryover, whereas liquid carryover is very sensitive to side arm extraction rates in a very small diameter ratio T‐junction.

“…Such adaptations include reducing the side arm/main arm diameter ratio (e.g. Azzopardi et al, 1988;Shoham et al, 1989;Walters et al, 1998;Van Gorp et al, 2001), which tends to promote more gas-dominated flow in the branch, essentially related to the reduced liquid passage time. The other natural extension to enhance the flow split at a T-junction is to simply rotate the side arm around the main branch, thus utilising gravity and the phase density differences.…”
