Numerical investigation of side arm gas volume fraction in two phase T-junction

Journal of Mechanical Engineering and Sciences, 2016
T-junction is commonly installed at the offshore production header as a separator to tap produced gas for downstream process operation. A major issue in the T-junction is the liquid carryover, where excessive liquid flows into the downstream process ...
