Numerical Modeling of Submerged Vane Flow.

Scours in rivers occur due to high flow velocities. In order to reduce scour, flow velocities need to be reduced. Submerged vane structures are effective in both reducing the flow rate and directing the flow. In this study, numerical modeling was made with submerged vane structures. Models of the measured flow velocities in the channel, where submerged vane experiments were performed before, were compared with the results of the submerged vane experiment by using the 3-dimensional computational fluid dynamics (CFD) method. In the present CFD model, continuity and momentum, turbulence model equations are applied. For the turbulence viscosity, k-ε turbulence model is used. The results of the present model are compared with the previous experimental work.
