Statistic modelling of turbulent hydrocarbon fluid flow separation in jointing channels

The paper is devoted to numerical simulation of space effects appearing with flow junction attachment and separation. Gas and oil flows through T-bends are considered. Algorithm based on two-parametric k-theory turbulence models is suggested. Among models there used k-ε models and original k-L model. Obtained results are analyzed and explained, practical recommendations on appropriate t-bend geometry are given.
