On the design of toroidal wind turbines

A novel toroidal-shaped axial wind turbine rotor has been designed utilizing Blade Element Momentum Theory (BEM). Initially, the rotor's unique geometry was modeled in STL format using the optimal lift and drag coefficients obtained from XFOIL data and an algebraic BEM algorithm. Preliminary simulations were conducted using a steady-state approach with a Moving Reference Frame. The findings suggest that the new rotor design is viable for wind energy extraction, although additional research is required to enhance its performance.
