Introduction

The world is shifting towards renewable energy sources to reduce our reliance on fossil fuels and mitigate the effects of climate change. One of the promising alternatives is the use of water turbines to harness the kinetic energy of water flows. In this study, we explore the performance of the Vortex gravitational water turbine type cross-blade type through computational fluid dynamics (CFD) simulation and experimental method. This turbine operates in a free vortex condition, where the flow of water rotates around the axis without an external force.

Background

The Vortex gravitational water turbine type cross-blade type is a unique design that utilizes the tangential rotation force of water to produce energy. The process starts when water flows through the inlet open and enters the basin in a tangential way, resulting in a strong vortex. This tangential rotation force of water is passed on to turbines to produce energy. The efficiency of this turbine is dependent on various factors, including the number of blades used.

Methodology

This study specifically analyzes the impact of the number of turbine blades on the efficiency of vortex gravitational water turbines. The variation in the number of blades tested is 5, 7, and 9 blades. The simulation results carried out using Ansys Fluent show that turbines with 9 blades provide the highest torque and efficiency in utilizing water flow. In CFD simulations, turbines 5, 7, and 9 blades each produces torque of 13.44 N.M, 14.6 N.M, and 21.89 N.M.

Experimental Test Results

Experimental test results also show the same tendency. Turbines with 5, 7, and 9 blades each produce torque of 12.75 N.M, 15.69 N.M, and 17.65 N.M, with an efficiency of 41.9%, 43.5%, and 45.1%. This data shows that as the number of blades used, the energy from the water flow that can be absorbed is greater, so that the torque and efficiency increases.

Analysis of the Impact of the Number of Blades on Turbine Efficiency

The increase in the number of blades in vortex gravitational water turbines has a significant implication to performance. More blades means that the area of capturing larger water flow, which allows more water kinetic energy to be utilized. In other words, additional blades help in channeling water flow more effectively, reducing energy loss due to turbulence, and increasing energy conversion efficiency.

Practical Application

In the context of practical application, this increase in efficiency is very important, especially for the development of a sustainable renewable energy system. Vortex gravitational water turbines can be used in remote areas as an alternative energy source, so this research makes an important contribution to the use of water resources on a sustainable manner.

Conclusion

The results of this study also open up opportunities for further development in the design of water turbines. Researchers and engineers can use these findings as a basis for further experiments and develop more optimal turbine design, and validate various physical parameters in real operations. Thus, this research not only provides insight into the performance of Vortex gravitational water turbines but also contributes to the development of more efficient and effective renewable energy technology.

Future Work

Overall, this study confirms that the optimal number of blades can significantly increase the efficiency of Vortex gravitational water turbines, which is an important step in the development of an environmentally friendly power plant system. Future work can focus on optimizing the design of the turbine blades to further improve efficiency and reduce energy loss.
