Theoretical Analysis of Vortex Turbine with a Circular Turbine House with Variations in the Diameter of the Exhaust, Water Level, and Runner Diameter

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 most promising alternatives is hydroelectric power, which harnesses the energy of moving water to generate electricity. However, traditional hydroelectric power plants require a significant amount of water flow and head to operate efficiently. In this context, vortex turbines offer a promising solution, as they can generate electricity from water sources with low water levels. This study aims to analyze the design of a vortex turbine with a circular turbine house, exploring the effects of variations in the diameter of the exhaust, water level, and runner diameter on its performance.

Background

Vortex turbines are a type of hydroelectric power plant that utilizes the energy of a whirlpool current to generate electricity. The concept of vortex turbines is based on the principle of a potential vortex, which is a type of fluid flow that occurs when a fluid is accelerated through a narrow channel. In the case of a vortex turbine, the fluid is water, and the narrow channel is the exhaust channel at the bottom of the turbine house. As the water flows through the exhaust channel, it creates a whirlpool current that drives the turbine blades, generating electricity.

Methodology

This study uses a potential vortex theorem similar to the free vortex phenomenon to analyze the performance of a vortex turbine. The theorem is applied to a micro hydroelectric power plant with low water level, which is a common scenario in many regions. The parameters that affect the speed of fluid rotation are investigated, including:

Diameter of the exhaust channel at the bottom of the center of the container: The diameter of the exhaust channel affects the velocity of the water that comes out, which ultimately affects the rotational speed of the fluid.
Water level (head): Water level determines the water potential energy available to produce a vortex.
Runner diameter (turbine blade): Runner diameter affects the efficiency of turbines in capturing energy from vortex currents.

Results

The results of the analysis show that the highest ideal theoretical water power potential is found in the fifth exhaust channel (Orifice 5) with a value of 12.58 watts. The best power and efficiency of the turbine is obtained in the fifth exhaust channel with the use of the A2 runner, which is 11.38 watts and 88.58%, respectively.

Deeper Analysis

The results of this study indicate that vortex turbines with the right design have the potential to produce electrical energy from water sources with low water levels. This has important implications for the development of renewable energy sources in the regions with limited water sources. The study also highlights the need for further research and development to optimize the design of vortex turbines and improve their efficiency.

Conclusion

Vortex turbines with the right structure of the container can utilize the vortex of gravity that is formed by water with a low water level. This study shows the potential use of vortex turbines as a reliable and efficient renewable energy source. With further development, Vortex turbines have the potential to be an interesting solution for generating electrical energy in areas with limited water resources.

Future Directions

This research can be further developed by conducting numerical simulations or experimental testing to validate theoretical analysis results. In addition, turbine design optimization and energy collection system can increase the efficiency and output of vortex turbine power. The study also highlights the need for further research on the effects of different materials and designs on the performance of vortex turbines.
