An Investigation on the Flow Characteristics in the Cross-Flow Turbine-T15 300

Abstract

A 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 turbine

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, 35o and

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 41o and 45 mm respectively. These

results are in good agreement with experimental data from previous studies.
