This study proposed a new thin cambered bent biomimetic wind turbine design that adopted the 3D geometry of the wing of a Borneo camphor seed sample. The wings of the Borneo camphor seed are thin, cambered, and bent. The unique geometry and orientation of the wings cause the seed to autorotate during propagation, subsequently slowing down its falling speed. It was presumed that by mimicking the wings of a Borneo camphor seed, a high-performance biomimetic wind turbine design could be proposed since the wind turbine, and Borneo camphor seed shares a similar rotating mechanism. Computational fluid dynamics was adopted to predict the power coefficient, thrust coefficient, and torque of the proposed biomimetic wind turbine models. The results show that the highest power coefficient was 0.3861 for the biomimetic wind turbine model, which is 20.14% higher than that of a benchmark case when the fold axis and fold angles are equal to 30° and 30°, respectively. The findings of this study concluded that the proposed biomimetic wind turbine design is cost-effective and worthy of further investigation.

“…The model had external parameters that can affect the performance like moisture and fatigue response, which can be considered as weaknesses of the model. A research was conducted by Chu and Chong [5], that was concerned the study of the performance of bio-inspired horizontal-axis wind turbine inspired by "Dryobalanops aromatic seed" as shown in Figure 6. To generate the 3-D design of the blade, different photos of the seed were taken in various perspective angels.…”

In the firm belief that the world needs green, renewable and more efficient energy resources, the present paper is concerned with developing a new design for horizontal-axis wind-turbine (HAWT) blades. The flower of Nelumbo nucifera (Sacred Lotus) was the motive for the present design of a three-blade wind turbine. Nelumbo Nucifera flower has an aerodynamically appropriate structure, which qualifies the flower to be the nature-inspiration for the present research. A computational fluid dynamics (CFD) simulation was applied in order to ensure the ability and eligibility of the proposed solution and estimate real world's results. The performance of the blade airfoil can be improved by applying the Lotus flower's structural design and modifying the blade straightening. The experimental findings demonstrated performance enhancement by 31.7% compared to NACA 2412 airfoil.

The aim of this paper presents an unsteady numerical investigation of a novel biologically inspired vertical axis wind turbine. The simulation was conducted in 2D using the sliding mesh technique with non-conformal mesh spatial discretisation via FLUENT. Grid sensitivity study on mesh density and turbulent transport model indicated that fine mesh and medium converged well with trivial difference. SST and k-ω model presented stable behaviour and indicated good agreement. SST were chosen for the rest of the simulation. The proposed wind turbine was simulated at five different moderate tip speed ratios under the influence of freestream velocity U∞=8m/s. The highest moment coefficient is generated at tip speed ratio λ=1.3, which is Cm=0.1886 with a stable positive moment coefficient after 480°. The proposed turbine responded well at λ=1.3 and λ=1.7 with power coefficient result of Cp=0.245 and Cp=0.262 respectively. The effect of wake and voracity on the turbine at subjected tip speed ratios is studied. Wake regions induced by the leading edge of the aerofoil impacted the performance of the following blade. Furthermore, due to the less wake effect trailed by the leading edge at λ=1.3, it generates higher moment than λ=1.7. Since the proposed blade has a fixed 4° angle of attack, it was sensible for the turbine to experience such wake and vorticity effect.
