Abstract:
The design and fabrication of a small-scale Archimedean screw turbine is presented in this study. The Archimedean screw turbine is a type of hydrokinetic energy conversion system that harnesses the kinetic energy of flowing water and converts it into mechanical power. This technology offers several advantages, including simplicity, robustness, and the ability to operate in low head and low flow rate conditions.
The objective of this research is to develop a small-scale Archimedean screw turbine suitable for applications in small rivers, streams, or irrigation canals. The design process involves the optimization of various parameters, including the screw pitch, blade angle, and diameter, to maximize power output while considering the limitations of available resources and manufacturing techniques.
Computer-aided design (CAD) software is utilized to model and simulate the turbine's performance under different operating conditions. Computational fluid dynamics (CFD) analysis is employed to evaluate the flow patterns, pressure distribution, and efficiency of the turbine. The results from the simulation are used to refine the design and improve the turbine's performance.
Based on the optimized design, a small-scale prototype of the Archimedean screw turbine is fabricated using readily available materials and manufacturing processes. The construction process involves the assembly of the screw blades, support structure, and power transmission mechanism.
The findings of this study provide valuable insights into the design and fabrication of small-scale Archimedean screw turbines, contributing to the development of sustainable and renewable energy solutions. The future work on this project includes the testing of the prototype under controlled laboratory conditions and in real life location as well, and evaluating its performance in terms of power output, efficiency and stability. The research outcomes can serve as a basis for further optimization and implementation of these turbines in various small-scale hydrokinetic applications, such as rural electrification, water pumping, and off-grid power generation.
