Abstract
Gravity separator tanks are used to separate oil from water in treatment units.
Achieving the best flow uniformity in a separator tank will improve the maximum removal
efficiency of oil globules from water. In this study, the effect on hydraulic performance of
different baffle structure positions inside a tank was investigated. Experimental data and 2D
computation fluid dynamics were used for analysis. In the numerical model, two-phase flow
(drift flux model) was used to validate one-phase flow. For laboratory measurements, the
velocity fields were measured using an acoustic Doppler velocimeter. The measurements were
compared with the result of the computational model. The results of the experimental and
computational simulations indicate that the best location of a baffle structure is achieved when
the standard deviation of the velocity profile and the volume of the circulation zone inside the
tank are minimized.
