Also available at: http://www.scirp.org/journal/jpeeA study on the flow characteristics in the cross-flow turbine model T15 300 has been conducted. The study was designed to examine the fluid flow trajectory in the tur-bine and identify areas for further improvement. Computational fluid dynamics (CFD) approach was employed and the results were compared with experimental data. The simulation study was conducted at guide vane angle of 20o, 30o, 35oand 41o. The shaft diameter was set at 30 mm, 45 mm, 60 mm, and 75 mm for each head while the head was maintained at 50 m. The flow characteristics were determined using particles trajectory.The research findings showed that the optimal vane angle and shaft diameter for cross-flow turbine were 41oand 45 mm respectively. These results are in good agreement with experimental data from previous studies.enCross-Flow TurbineCFDHydropowerTrajectoryTurbineDrag forceArticle
