The document describes the design and computational fluid dynamics (CFD) analysis of a spiral wind turbine (SWT) with varying wind speeds. Key points:
- SWT is a new type of horizontal axis wind turbine with two spiraling blades wrapped around a teardrop-shaped shell, designed to harness both lift and drag forces from wind.
- A 3D SWT blade model was designed in AutoCAD Fusion 360 and meshed. CFD analysis using k-epsilon turbulence modeling was performed at wind speeds of 1, 5, 9, and 15 m/s.
- Results show SWT extracts more power than conventional turbines at lower wind speeds. Pressure is highest around the blade and lowest
