“…L Tenghiri et al [4] presented a typical design methodology of the rotor blades of a small wind turbine with a power generation of 11 kW. He determined optimum blade geometry (chord length and twist angle distribution) using optimum rotor theory and the wind turbine blade performance was assessed using Q-blade software.…”

Wind power is a clean energy source that we can rely on for long term use. A wind turbine creates reliable, cost effective pollution free energy. A Horizontal axis wind turbine (HAWT) with three blades having aerofoil profile NACA 2421 is modelled in CAD software and the performance of the turbine is investigated numerically using 3D CFD Ansys 18.1 software at rotor speeds varying from 1 to 7.5 Rad/sec at wind speeds ranging from 8 to 24 m/s. In order to ensure the turbine blades do not fail due to pressure loads and rotational forces, Fluid structure interaction is carried out by importing the surface pressure loads from CFD output on to static structural module, the rotational velocities are also imparted on the blades and FE analysis is carried out to estimate the equivalent von-Mises stress for structural steel as well as aluminium alloy. It is found that aluminium alloy blades are preferable than the structural steel blades. At high rotor speeds, stresses in the structural steel exceeding the yield strength limit. For aluminium alloy the stresses are below the yield strength limit.

“…Initially, the design wind speed, V Design is defined based on the international standard of IEC61400-2 for designing SWT. The V Design for SWT is 1.4 times the mean annual wind speed (MAWS) (Tenghiri et al, 2018). To be consistent, the V Design is set at 4 m/s for 2-3 m/s average wind speed in Malaysia.…”

The global market for wind turbines has kept on emerging in the former decade. The large wind turbines have all advanced over the years to such a degree, to the point that the innovation is significantly developed. Whereas, the technology for small wind turbines has not fully-fledged like the large wind turbines due to the absence of such methodical research and development. Within a short span, a base development rate of 12% is foreseen to proceed due to advanced research, and the productiveness is predicted to reach around 1.9 GW by 2020. Since, a major portion of the globe is not having sufficient wind potential, the use of small wind turbines provides the exclusive opening of entering an untapped market without any environmental degradation. As Malaysia is promoting renewable energy sources for economic and environmentally friendly energy sustainability, this research aims at introducing small wind turbine technology because of its prevailing low wind speed. The future of the small wind turbines in Malaysia depends upon the capital cost per kW of the small wind turbine installation and the energy cost per kWh of the energy produced. Hence, keeping these two factors in mind, small scale wind turbines are designed using a blade element momentum theory based on the prevailing average wind speed in Malaysia.

“…For instance, Kenway and Martins [12] showed a possible 3-4% increase in the power output using the optimum blade shape determined by a multidisciplinary design feasible (MDF) approach, and Clifton-Smith and Wood [13] employed a differential evolution method focusing on improving the turbine starting performance. Other multi-criteria design methods aim to solve an optimization problem of minimizing blade vibration and maximizing the output power under the constraint of sufficient blade structure stability [14][15][16][17].…”

We experimentally explored the impact of a wind turbine with truncated blades on the power output and wake recovery, and its effects within 2 × 3 arrays of standard units. The blades of the truncated turbine covered a fraction of the outer region of the rotor span and replaced with a zero-lift structure around the hub, where aerodynamic torque is comparatively low. This way, the incoming flow around the hub may be used as a mixing enhancement mechanism and, consequently, to reduce the flow deficit in the wake. Particle image velocimetry was used to characterize the incoming flow and wake of various truncated turbines with a variety of blade length ratios L / R = 0.6 , 0.7, and 1, where L is the length of the working section of the blade of radius R. Power output was obtained at high frequency in each of the truncated turbines, and also at downwind units within 2 × 3 arrays with streamwise spacing of Δ x / d T = 4 , 5, and 6, with d T being the turbine diameter. Results show that the enhanced flow around the axis of the rotor induced large-scale instability and mixing that led to substantial power enhancement of wind turbines placed 4 d T downwind of the L / R = 0.6 truncated units; this additional power is still relevant at 6 d T . Overall, the competing factors defined by the expected power reduction of truncated turbines due to the decrease in the effective blade length, the need for reduced components of the truncated units, and enhanced power output of downwind standard turbines suggest a techno-economic optimization study for potential implementation.
