Innovation application: Vertical Axis Wind Turbine Efficiency

Title Vertical Axis Wind Turbine Efficiency

Wind power is one of the most common types of environment-friendly power generation. Horizontal axis wind turbines and vertical axis wind turbines are the most commonly used solutions for such power extraction. Usually the vertical axis wind turbines can generate electricity at a variable wind direction without any active or passive system for alignment of turbine position and wind direction. The main components of the vertical axis turbines, such as the generator and turbine construction support, are placed close to the ground, so the design would be simpler and lighter, and maintenance would be more convenient and cost-effective.

Keywords vertical axis wind turbine, wind power, the power coefficient

Description of the technology

We offer modeling and analysis of interaction phenomena of a vertical axis wind turbine and air flow using the SolidWorks software. The results will determine the power coefficient, torque and other characteristics of the turbine blades under aerodynamic forces for the selected turbine design at various initial conditions of the flow. In fluid regions SolidWorks Flow Simulation solves the Navier-Stokes equations. Calculations can be made for both laminar and turbulent flows. An original Two-Scale Wall Function (2SWF) approach is used for the wall treatment. A multi-parameter optimization of the turbine structure can also be performed.
