| description | This research discusses about the process of numerical simulation of twophase
liquid-liquid in T-junction. The flow of two liquid-liquid phase which
became the focus of study is a mixture of kerosene and water flow. The flow of
this mixture in the input into the T-junction is separated for each phase. Kerosene
phase directed to the branching point T-junction which is called a branch and the
other direction for water phase is called the branching point of the run. Phase
separation efficiency is influenced by the geometry T-junction which is focused
on the influence of radius of bend at the point of branching angle and diameter Tjunction
branch.
The first observation conducted on the two-phase flow numerical simulation
in T-junction using Fluent software is to model multiphase flow Volume of Fluid
(VOF) and the turbulent flow model κ-ε. Flow simulation is done in T-junction
with inlet diameter 36 mm radius of bend having 5 mm, 15mm and 25 mm and
diameter of branch 19 mm, 26 mm and 36 mm with a mixture phase superficial
velocity 0,20, 0,27, 0,34, 0,41, 0,48, 0,55 and 0,62 m /s and fraction volume of
water (water cut), 0,50, 0,56, 0,59, 0,61, 0,63, 0,64 and 0,65. Numerical
simulation results are verified by the experimental results for branch diameter 19
mm.
The quality of kerosene which enter at the inlet T-junction from numerical
simulation and test results have value percentage deviation of the average quality
of kerosene on the ujiing data is 3,6%. For condition Db = 19 mm, the separation
efficiency in branch T-junction has value the average percentage deviation of the
numerikal simulation results of testing on the condition of R = 5 mm, 15 mm and
25 mm respectively was 14,7%, 3,6% and 3,8%. For condition Db = 26 mm and R
= 5, 15 and 25 mm, the average efficiency of separation are 0,76, 0,84 and 0,85
respectively. For condition Db = 26 mm and R = mm, 15 mm and 25 mm, the
average efficiency of separation are 0,74, 0,83 and 0,87 respectively. For
condition Db = 36 mm and R = mm, 15 mm and 25 mm, the average efficiency of
separation are 0,85, 0,91 and 0,88 respectively. |
