The Archimedes wind turbine boasts an innovative blade design with the potential of harvesting energy from wind with much more efficiency. The blade design utilizes both lift and drag forces, and boasts several other advantages over conventional horizontal axis and vertical axis wind turbines, which implies higher power production efficiency and a possibility of being used in urban areas with attendant low wind speed regimes for small scale power generation, being more portable. However, there exists a dearth of experimental reports on the Archimedes wind turbine besides CFD simulations, to observe and study its real-life performance and power production potential. This paper is an experimental report on the design and wind test of the Archimedes wind turbine prototype, together with calculations made to gauge its tip speed ratio, power output and energy production potential. To show the viability of the prototype, the power produced is used to charge a HTC Desire cell phone, which proves that it can be relied upon to meet the title objective of small scale power storage with a power bank. Results are thereafter compared to other published work and show relatively good agreement. Minor deviations are attributed to the challenges encountered during the fabrication process.

Lift And Drag

The looped airfoil wind turbine (LAWT™) is a patented new technology by EverLift Wind Tecnology, Inc. for generating power from wind. It takes advantage of the superior lift force of a linearly traveling wing compared to the rotating blades in conventional wind turbine configurations. Compared to horizontal and vertical axis wind turbines, the LAWT™ can be manufactured with minimal cost because it does not require complex gear systems and its blades have a constant profile along their length [1]. These considerations make the LAWT™ economically attractive for small-scale and decentralized power generation in rural areas. Each LAWT™ is estimated to generate power in the range of 10 kW to 1 MW. Due to various advantages, it is meaningful to determine the maximum power generation of a LAWT™ by optimizing the structural layout. In this study, CFD simulations were conducted using ANSYS Fluent to determine the total lift and drag coefficient for a cascade of airfoils. The k-kl-ω turbulence model was used to account for flow in the laminar-turbulent transition region. Given the lift and drag coefficients and the kinematics of the system, an analytical formula for the power generation of the LAWT™ was developed. General formulas were obtained for the average lift and drag coefficients so that the total power could be predicted for any number of airfoils in LAWT™. The spacing between airfoils was identified as the key design parameter that affected the power generation of the LAWT™. The results show that a marked increase in total power can be achieved if the optimum spacing between the airfoils is used.

Vertical Axis Wind Turbine

The small-scale vertical axis wind turbine is designed and modeled in this project, considering all aspects of wind turbine such as Blade design, stator design, rotor design and converter system design. Electric Power has become a prime necessity for any country for economic development. The conventional fuel sources for power generation are depleting fast. The favorable alternatives are renewable energy sources. Although more invention has to be carried out in the field of renewable energy sources, every little effort in this direction may provide a solution to reach most economical power generation point. Hence the same topic was selected for Masters Project. The goal of this project is to design a small scale Vertical Axis Wind Turbine, which is capable of producing electrical power even with low wind velocity. It can be placed on road dividers, sidetracks of train or remote places i.e. villages, military camps, where it is not economical to transmit power from power plants. Implementation of such project would reduce the dependence of an industry or remote houses, on electricity board.
