Abstract In recent years dynamic induction control has shown great potential in reducing wake-to-turbine interaction by increasing the mixing wake. With these wake methods thrust force will vary time. If applied to a floating offshore wind turbine, it cause platform move. this paper effect of Helix approach on DTU10MW turbine TripleSpar and its is evaluated. When at Strouhal equal 0.25, yaw mov...

This paper presents results of experimental investigations and numerical simulations a vertical-axis H-type wind turbine, considering the influence propeller blade pitch angle on turbine characteristics. An innovative airfoil profile based modified symmetric NACA0015 was used as designed profile, which tested in tunnel over range Reynolds numbers from 50,000 to 300,000. The phenomenon angle-of-...

This article presents the analysis of performance a flexible wind turbine blade. The simulation is based on 3 m span blade prototype. has surface and cam mechanism that modifies aerodynamic profile adapts to different configurations. was built with fiberglass composite, internal consists structure actuated an eccentric cam. deforms five sections blade, airfoil geometry for each section measured...

Rüzgâr türbinlerinden elde edilen enerji miktarı her geçen gün artmaktadır. türbinlerinin güç çıkışlarını etkileyen faktörlerden birisi de kanat profilleridir. Bu çalışmada rüzgâr türbinlerinde kullanılan farklı (NACA 0009, NACA 2415, 4415, 4424, 6412, 6415, 24112, FX 63-137, GOE 795, NREL’s S824, SD 5060, SG6040) profillerinin Qblade yazılımı kullanılarak simülasyonları oluşturulup sayısal ana...

In this study, airfoil shape optimization of a wind turbine blade is performed using the ANSYS Fluent Adjoint Solver. The aim process to increase output power, and objective function maximize lift drag ratio (Cl/CD ). This study applied NREL phase VI turbine, therefore, S809 used as reference profile. First, for validation numerical model, steady-state simulations are carried out at various ang...

The rise in energy requirements and its shortfall developing countries have affected socioeconomic life. Communities remote mountainous regions Asia are among the most by deprivation. This study presents feasibility of an alternate strategy supplying clean to areas consisting pristine mountains forest terrain. Southeast has a much-diversified landscape varied natural resources, including abunda...
