Numerical Simulation of Drag Cum Lift Horizontal Axis Wind Turbine
摘要
The current research focuses on static computational fluid dynamics simulations of our patented Horizontal Axis Wind Turbine design. The innovative concept concentrates on combining lift and drag forces, thereby eliminating the issue of reverse drag when the blade panel is moving in opposition to the wind. The design focuses on converting reverse drag into an effective lift force. The investigation used the finite volume-based software Ansys Fluent at various blade positions. The simulations were performed using the pressure-based solver and the realizable \(k-\epsilon \) turbulence model. The simulations were conducted for a quarter of the rotation, as the blades acquired the same initial position after each quarter by continuously adjusting their angle of attack using advanced controls. The simulation results demonstrate a significant resistance by the drag force and an upward perpendicular force by the lift, with both forces contributing to energy production.
