Abstract: Three dimensional model FLUENT is used to simulate and analysis of flow pattern around submerged vanes placed in front of the diversion entrance, located at 115°position with diversion angles of 45 degree, in 180 degree bend with rigid bed. Computations are performed using Reynolds Stress Model. Comparison of the predicted velocity field with laboratory measurements indicates that the model captures experimental trend with reasonable accuracy. The numerical model are used to elucidate the complex 3D flow field in front of intake, including flow dividing, zones of separation and secondary flow around vanes.
