Abstract
Providing purified water in marine and domestic applications, especially in remote areas regarding fossil fuels environmental pollutants, makes it hard to use conventional energy sources. Therefore, the present research seeks to construct a water purification system by using reverse osmosis technology supplied by a novel wind turbine driven by a permanent magnet synchronous generator. To reach this goal, an efficient high torque wind turbine was designed with new butterfly blades, determining the lift and drag forces along with creating twisting angles in blades. The blades were initially designed in SolidWorks software. Then, the computational fluid dynamics principles were simulated in the COMSOL5.2a environment by utilizing the k-ω pattern and multi-reference coordinate axis method. A laboratory prototype was implemented to verify the theoretical calculations, simulation analysis, and validity of the wind turbine. To ensure the sufficient capability of the system in worse situations, the performance of the turbine system at a low wind speed of 4 m/s was evaluated. The results showed that a maximum power factor of 0.29 was obtained, making the micro-turbine appropriate for both marine and domestic sweetener systems.
