6 FAQs about [Generator blade parameters]

How many parameters does the blade profile parameterization method use?

The blade profile parameterization method uses 13 parameters. They are presented in Fig. 2. In order to simplify the computational process, the blade profile is oriented and scaled, so the centers of circles of leading and trailing edges are situated at X = 0; Y = 0 and X = 1; Y = 0 respectively.

Can rotor blade geometry maximize energy production of wind turbines?

The general objective of the present work is to define and evaluate a design methodology for the rotor blade geometry in order to maximize the energy production of wind turbines and minimize the mass of the blade itself, using for that purpose stochastic multi-objective optimization methods.

What is a parametric method of turbine blade profile design?

Geometry of blade profile plays an important role in the processes of coarse droplets formation in blade passages (droplets separation on blade surfaces, liquid film breakup near trailing edge etc). In the first part of this paper a parametric method of turbine blade profile design is observed. It uses Bezier curves in order to form profile shape.

What is a wind turbine blade?

The blade is the main component of the wind turbine, which extracts the energy from the wind, and it contributes 20–25% of the wind turbine’s overall budget [ 34 ]. Therefore, it is essential to optimize the design of the wind turbine with a maximum power coefficient under the design conditions.

What is the design process of a wind turbine blade?

The design process of a wind turbine blade can be divided into two steps: aerodynamic design and structural design. The aerodynamic design consists in the selection of optimal geometry of the blade external surface (blade geometry), which is defined by the airfoil family and the distributions of chord, twist angle and thickness.

How to design a vortex generator on a wind turbine blade?

Factors to consider while designing a vortex generator on a wind turbine blade are its shape, the distance between two adjacent vortex generators, and their angle of attack for the wind. The vortex generator’s thickness is always 10–15% of the boundary layer thickness .
