This paper presents the aerodynamic design and economical evaluation of a 200 kW site specific wind turbine for the province of Semnan in Iran. By designing site specific wind turbines, the cost of energy which is calculated out of the annual energy production and also the cost of manufacturing the rotor are minimized. The aerodynamic design is based on the well-known blade element momentum...

One well-known obstacle facing most sources of renewable energy is the significantly decreased energy density with respect to fossil fuels. Energy density of wind power is further penalized by the need for wind turbines to be spaced far enough apart to not interfere with one another. Conventional horizontal axis wind turbines (HAWTs) must be spaced far apart [3–5 turbine diameters in the crossw...

Clean energy harvesting and usage has gained considerable attention in the last few decades. While the horizontal axis wind turbines have been used extensively, they have certain defects and functional limitations. In the present paper, a novel oscillatory wind turbine is proposed. The conceptual design of the new turbine together with its configuration is explained. Dynamical equations of the ...

Horizontal Axis Wind Turbine (HAWT) rotor is a system whose components are particularly exposed to fatigue damage, due non-uniform winds and the rotating nature of rotor. Individual Pitch Control (IPC) can help alleviating loads on blades by independently from each other their longitudinal axis. However, reducing damage often compensated an increase in pitch activity, damaging blade actuators. ...

This study investigated the performance and aeroelastic characteristics of a wind turbine blade based on strongly coupled approach (two-way fluid structure interaction) to simulate the transient FSI[1] responses of HAWT[2]. Aerodynamic response was obtained by 3D CFD-URANS approach and structural response was obtained by 3D Finite element method. ...

This paper presents an optimization method for the structural design of horizontal-axis wind turbine (HAWT) blades based on the particle swarm optimization algorithm (PSO) combined with the finite element method (FEM). The main goal is to create an optimization tool and to demonstrate the potential improvements that could be brought to the structural design of HAWT blades. A multi-criteria cons...

The aim of this study is the aerodynamic degradation a three-bladed Horizontal Axis Wind Turbine (HAWT) under influence hailstorm. importance and originality are that it explores performance an optimum wind turbine blade during hailstorm, when hailstones raindrops present. commercial Computational Fluid Dynamics (CFD) code ANSYS Fluent 16.0 was utilized for simulation. first step calculation ge...

Diffuser augmented wind turbines (DAWTs) can increase mass flow through the rotor substantially, but have often failed to fulfill expectations. We address high-performance diffusers, and investigate the design requirements for a DAWT rotor to efficiently convert the available energy to shaft energy. Several factors can induce wake stall scenarios causing significant energy loss. The causality b...
