Aerodynamic Performance of a Double-H Type Vertical-Axis Wind Turbine: Designed by a Stream-Tube and CFD Method

Article Preview

Abstract:

The thesis improves a stream-tube method based on solidity modification and CFD method used to predict both steady and unsteady aerodynamic performance of the fixed-pitch vertical-axis with double straight-blades type of turbine designed by FengFa Technology for wind conversion. Numerical results of predicting instantaneous blades forces and power output of the rotor showed good agreement with the test data, which showed that the present model is suitable for the design and optimization of such kind of turbine.
