In recent times, gravitational water vortex power (GWVP) technology has shown rapid development because of its simple design and adaptability to a wide range of flow conditions, even for low-head hydropower applications. In this study, the performance of a GWVP plant was investigated, particularly with respect to the blade number in the vortex turbine and draft tube added as a modification of the conical-shaped vortex basin. Computational fluid dynamics (CFD) simulations have been extensively used to assess hydraulic efficiency while observing the flow field. The ANSYS CFX software was used as the simulation tool, and the CFD setup was validated prior to simulating the newly designed GWVP plant. The effect of the blade number in the vortex turbine was investigated using, 5-,6-,8- and 10-blade turbines, while the effect of the draft tube was studied using straight and conical designs. Finally, the eight-blade turbine achieved a maximum efficiency of 57% while maintaining a stable vortex air core. The addition of a small draft tube in the vortex basin increased the efficiency up to 60%, as it was able to recover the pressure gradually at discharge.
