Computational fluid dynamic analysis of draft tube used in hydro power plant

Abstract

At present scenario the cost of hydroelectricity is relatively low, making it a competitive source of renewable
electricity. It is also a flexible source of electricity since amount produced by the plant can be changed up or down very
quickly to adapt to changing energy demands. Main components of hydropower plant are dam, penstock, turbine, and
generator and draft tube. This paper contains modeling and analysis of existing draft tube for hydropower plant. Computation
fluid dynamics result shows the velocity outlet. For future work efficiency of the draft tube will be increased by modifying
the dimensions of draft tube.
