Abstract

Hydropower is a superior energy extraction approach, which has been made to work based on renewable energy sources. In the generation of hydropower, Gravitational Vortex Hydropower (GVHP) plays a predominant contributor role because of its free turbulence-relayed energy utilization concept and flexible as well as compact size. Owing to the huge contribution of GVHP in the hydropower sector, multi-objective-based investigations have emerged. However, there is still insufficient literature available for the technology to precede optimum turbine blade design. Two important categories are involved in these multidisciplinary investigations, in which the first phase, a numerical investigation has been done using ANSYS to identify the location of maximum tangential velocity in a conical basin with different notch angles, conical angles, basin shapes, anddiameters. In this second phase, the focal aim is to carry out the numerical investigation on Gravitation Vortex Turbine Blades (GVTB) for the different geometry in order to get the optimum power output with a high structural lifetime through HSI (Hydro–Structural Interaction) computation. The entire conceptual designs of this SGVHP and its hydro-rotors are modeled with the help of CATIA. ANSYS Fluent is a CFD (Computational Fluid Dynamics) numerical tool, which is primarily used in this paper for all the hydrodynamic analyses. Finally, the standard analytical approaches are used for the comparative determinations of thrust production by hydro-rotors, power extraction by hydro-rotors, and propulsive efficiency for the selection process of best hydro-rotors. HSI analyses are additionally carried out and thereby the suitable lightweight material is picked.

Highlights

Electrical energy is always playing a predominant role in the day-to-day activities of people so it must be investigated thoroughly in order to hold its availability at a good level
The integrative effects are comprised of prised of both negative and positive conclusions, wherein the positive conclusion is that both negative and positive conclusions, wherein the positive conclusion is that the impact the impact force on the rotor is high so the possible energy extraction is quite lofty and the force on the rotor is high so the possible energy extraction is quite lofty and the negative negative conclusion is that the possibility of structural failure is higher due to its greater conclusion is that the possibility of structural failure is higher due to its greater fluid density
The conceptual designs of all the four hydro-rotor models are executed with the help of CATIA, in which the dimensions of Gravitational Vortex Hydropower (GVHP) and various rotors are obtained from the previous reference papers

Summary

Introduction

Electrical energy is always playing a predominant role in the day-to-day activities of people so it must be investigated thoroughly in order to hold its availability at a good level. Electrical energy creation through hydro fluids is very complicated and superior when compared with other sources such as solar systems, windmill systems, etc. This is because the hydro fluid is much denser. Sustainability 2022, 14, 727 such as solar systems, windmill systems, etc This is because the hydro fluid is much denser than other electrical energy production-based fluids so the impact on energy conthan other electrical energy production-based fluids so the impact on energy converters verters such as turbines, sheets, etc., is greater. The integrative effects are comprised of prised of both negative and positive conclusions, wherein the positive conclusion is that both negative and positive conclusions, wherein the positive conclusion is that the impact the impact force on the rotor is high so the possible energy extraction is quite lofty and the force on the rotor is high so the possible energy extraction is quite lofty and the negative negative conclusion is that the possibility of structural failure is higher due to its greater conclusion is that the possibility of structural failure is higher due to its greater fluid density
