Numerical simulation has been made of incompressible two-layer stratified flow containing immiscible fluids in a duct whose cross-sectional area varies periodically in the streamwise direction. The results correspond to oil-water flow of fixed volumetric flow rates. Solutions were obtained for a range of Froud number. Two configurations of the duct were considered: duct with fins attached to the bottom plate and duct with fins attached to the top plate. These configurations represent an idealized model of a certain type of locking and regulating device. The results demonstrate the effect of the fin location on total volumetric flow rate.
