Flow Simulation of a New Horizontal Axis Wind Turbine with Multiple Blades for Low Wind Speed

Abstract In this paper, a new design of small horizontal-axis wind turbine is introduced. The based on the authors’ patent, which uses permanent magnets impeded into shroud that holds rotor blades. generator coils are installed fixed diffuser houses and acts as concentrator. Therefore, has no hub direct coupling for electricity generation. main features have been explored to highlight advantages with focus how can be integrated recent development green buildings. effect increasing number blades blade chord distribution performance investigated turbine. Initial analysis were carried out using Blade Element Momentum method CFD simulations identify examine flow characteristics. results showed further energy extracted from if size increases at location reduces low Tip Speed Ratio TSR within range 1.5–3. Furthermore, having more significantly increase power coefficient extend operation high coefficient. blades, however, optimised achieve maximum relative cost. Adding flanges surrounding speed.
