Pipeline tee mixing quality has been computed with a computational fluid dynamic (CFD) code. In particular, the kappa-epsilon model has been used to calculate the second moment of an inert tracer downstream from the tee mixer. The range of values covered for the steady, single phase, turbulent flow are a jet-to-pipe diameter ratio of 0.026 < d/D < 0.36 and velocity ratio 2 < U/V < 10. The results indicate that the turbulent model successfully correlates existing data and suggests a small adjustment to an existing similarity solution.
