Numerical Study of Damper Plate and Nozzle Effect on Vortex Turbine Basin for Increasing Flow Kinetic Energy Entering Turbine Rotor

The Gravitational Water Vortex Power Plant (GWVPP) is a small-scale hydroelectric power generator that makes use of the energy generated from vortex flow to turn turbine blades and generate electricity. In this research study, focus was on numerical analysis basin design GWVPP, which divided into three sections: section, transformer section. To support transformation process tangential speed axial in damper plate installed direct rotating flow. effect nozzle accelerating for optimizing also studied reduce blockage caused by process. results indicate designs with have lower velocity outputs due At rate 0.1 m3/s, presence reduces maximum rotation, but at 0.2 it prevents leakage surface. without optimal variation rates while m3/s.
