“…They obtained very similar results with BEM, CFD simulation and experimental data from wind tunnel tests, which confirms the validity of their results. Y. Khalil et al, [3] used an algorithm based on the BEM analysis to design and predict the behavior of a wind turbine with a 7 meter diameter and then applied CFD analysis, the results between them matched. Tahani M. et al, [4] used BEM theory and CFD simulation to compare with the experimental data from a Vestas V47 commercial wind turbine, they achieved similar results between the three methods.…”

“…Size of each chord along the radius for B1. (Khalil et al 2018) proposed a method to optimize and find the radial ai' and axial a induction coefficients, allowing them to find the best configuration to maximize output power. The spanwise blade tends to be thinner in the root zone, while the tip direction remains almost without change.…”

This article introduces a novel Induction Blade (IB) prototype modeled by Blade Element Momentum (BEM) theory, which develops higher torque during the starting phase for Horizontal Axis Wind Turbines (HAWT), especially for micro-turbines. The IB is composed of two parallel blades joined at their tips and roots, forming a distinctive hole in the space between the blades that generates a Venturi effect as air passes through. This phenomenon in the IB hole together with the extra lift generated by the area of the second blade produce extra valuable torque during the starting phase. We used Computational Fluid Dynamics (CFD) analysis to evaluate the aerodynamic properties of this design compared with a traditional blade design of the same radius. The IB and traditional prototypes were built (50W, diameter 0.62m, =9 and at speed rated 8m/s) by additive manufacturing in a 3D printer and their aerodynamic behaviors tested in a small wind tunnel (square section 0.7m x 0.7m). Our results using CFD analysis show that this novel IB produces up to 65% extra torque without losing output power for low wind velocity (5-8 m/s). IMPI (Mexican Institute of Industrial Protection) protects this prototype shape.

“…The BEM design method was used to calculate the chord length and twist angle of every blade element. For calculation of the blade aerodynamic forces the well-publicised BEM theory is applied, as [8] on the small wind turbines. Working along the blade radius taking small element, the sum of the aerodynamic forces can be calculated to give the overall blade reaction and thrust loads.…”

The development of wind power generation technology recognises the wind turbine blade design and manufacturing as crucial for its performance. The laboratory size wind turbine blade was analysed, considering the 3D printing plastic material for blades. Applying the structural dynamic equations of blades, the aero-elastic model of the rotating rotor and the numerical simulation method of the deflections are presented under the aerodynamic loads and centrifugal forces. Based on the parameters of aerofoil and the geometrical parameters of blade, 3D model of the blade was established with the modelling software. Then the model was introduced into computational flow dynamics software to carry out the loads on the blade and further into numerical structural analysis. The analysis was performed in two different software packages. Design of wind turbine blades depends on high precision, reliable and robust numerical predictions of performance where the plug-in software is found to be inadequate for nontrivial problems.
