AB  - The rising cost of fossil fuels has prompted a shift towards environmentally friendly alternative energy sources, leading to an expansion in the study of renewables. Wind turbines, specially those of the small-scale variety, have emerged as a promising solution for generating sustainable electricity, particularly in rural areas and for smaller consumers. This study focuses on the analysis of pitch angles for three-bladed horizontal axis wind turbines (HAWT) with a diameter of 1.35 m, classified as micro wind turbines. The analysis assumes incompressible and viscous flow, with shear stress transport (SST) equations closed by various turbulence models. The ANSYS program was used for conducting this analysis.

AB  - The usage of parts with free form surfaces is growing day by day, not only in the field of mechanical engineering, but also in the production of parts for everyday household needs. This implies the need for developing of new methods for the production of such parts. When it comes to machining, the most common cases of production are milling with ball end mill on numerically controlled machine tools. In this paper are presented different methods for mathematical description of free-form surfaces such as Bézier curves, B-spline curves and non-uniform rational B-spline.

AB  - The wind speed is one of the major parameter influencing the design of the wind turbine, which varies widely over the different part of the country and globe. So, significant research is going on for the design of wind turbine for low, medium and high wind speed. Currently, many researchers have started designing small-scale horizontal axis wind turbines (HAWT) in world, to adapt their use to households. The advantage is reflected in the simple and affordable construction, uninterrupted operation and satisfactory power that wind turbines create. An airfoil is defined as the cross section of a body that is placed in an airstream in order to produce a useful aerodynamic force in the most efficient manner possible. The cross sections of wings, propeller blades, windmill blades, compressor and turbine blades in a jet engine, and hydrofoils are example of airfoils. A computational study has been conducted on various airfoils to simulate flows at different Reynolds numbers (Re) and wind speed to provide understanding and guidance for other low Reynolds-number designs. The numerical computational method used in this study is a boundary element method (BEM) which is implemented in software Qblade. It is an alternative deterministic method which incorporates a mesh that is only located on the boundaries of the domain and hence are attractive for free surface problems. The airfoils investigated in this study include NACA 4412, NACA 63-415 and S809. Performances such as power, power coefficient and tip speed ratio were compared.
