“…The effect of diameter ratio is the most investigated parameter yet among others. A detailed review was given by Ejaz et al, [44] addressing critical findings in 1998 and state of the art theories that, diameter ratio improves phase separation but up to a certain limit. For instance, Saieed et al, [43] identified that 0.67 diameter ratio performed better than other diameter ratio T-junctions.…”

Whenever T-junctions are used in chemical processes and petroleum industries for two-phase separation, a maldistribution of phases is observed between outlets of the junction. Currently, the regular T-junctions are utilized in the industry due to which equipment downstream faces high liquid carryovers. Unfortunately, downstream equipment is not capable of handling high liquid carryovers and they trip frequently, consequently. This review manuscript summarizes the effect of different factors that influence phase separation in the T-junction. This article refers to the geometrical parameters, phase superficial velocity flow regimes encounter during the separation process, and different side arm modifications. This article is a contribution to this field as it summarizes and concludes all these factors comprehensively, to give a verdict on ways to improve phase separation. It is also recommended that the effect of side arm modifications or combinations must be explored for further understanding.

“…The maldistribution phase that occurs can be used as a useful tool in the partial separator phase (Ejaz;. In offshore oil drilling locations, a separator needs to separate crude oil from other elements (gas, water, mud) contained in the bowels of the earth (Suminar;& Nurcahyo, 2020).…”

“…The separator is shaped like a tube and is tightly closed against pressure and has only an inlet and outlet, and is equipped with a pressure gauge. The separation ratio is influenced by various factors including the pressure in each branch (sidearm and run arm), the mass inertia of the liquid, the flow pattern in the upstream section, and the geometry of the T-junction (Ejaz;.…”

This study aims to determine the separation of kerosene and water in a piping installation. It is very important to do research because it can reduce problems that arise in the distribution of drilling oil to further processing and distribution. T-Junction is a method used in this study, because the separator method is rarely used. The separation of kerosene and water types in the test using the T-Junction method, variations in downstream flow resistance of 42%, 57% and 72% resulted in a large kerosene separation efficiency of 100% at a mixed superficial velocity of 0.35 m/s, Jw= 0.25 m/s Jk = 0.10 m/s and at mixed superficial velocity 0.47 m/s, Jw = 0.22 m/s Jk=0.25 m/s, while 99% efficiency occurs at mixed superficial velocity 0 ,20 m/s , Jw= 0.10 m/s and Jk = 0.10 m/s. Water cut also greatly influences the phase separation. The lower the water cut, the higher the peak separation efficiency achieved

“…T-junction is a significant component of pipe network which is mainly used for combining, dividing, and mixing fluid flowing through the pipeline. Mixing of hot and cold fluid can be found in the cooling system in nuclear power plants, production, and distribution of oils and gases, and many other industries [1,2].…”

Temperature fluctuation occurs while mixing of hot and cold fluids in a T-junction due to incomplete thermal mixing. This temperature fluctuation can produce thermal fatigue at the weld area of the T-junction. The present study aims to numerically investigate the thermal mixing characteristics of hot and cold fluids in a T-junction. The realizable k-ε turbulence model is used with natural gas as the working fluid. Temperature distribution, mixing quality, and intensity of temperature fluctuation are evaluated and compared along with the mixing outlet. The inlet temperature difference and branch to main pipe flowrate ratio have a direct influence on thermal mixing. The higher temperature difference can reduce the thermal mixing performance. Thermal mixing increases with the increase of branch to main pipe flowrate. The intensity of temperature fluctuation is found within a short distance from the intersecting point of the two inlets. With the increase of distance along with the mixing outlet, the frequency of temperature fluctuation decreases, and thermal mixing increases.
