MODELING AND SIMULATION OF THE VERTICAL AXIS WIND TURBINE BY QBLADE SOFTWARE

Received 16 September 2020 Revised 13 October 2020 Accepted 12 December 2020 Wind energy is clean energy. This one is a viable alternative to the problems raised by nuclear waste management and greenhouse gas emissions. Vertical axis wind turbines present a lot of advantages for domestic applications, where wind flow conditions are intermittent, omnidirectional, unsteady and turbulent. In this work, we discuss VAWT type wind turbines. More specifically, we present the geometry and aerodynamic characteristics of the blade profiles. The acting forces and DMS multiple flow tube models are also studied. This work gives Qblade software as a simulation method to optimize the behaviour of the blades from the selected NACA profiles. The analysis first goes through the design of the blades then it calculates the forces on the blade and coefficients of lift, drag and fineness. At the end of this article we have the DMS simulation of the VAWT turbines, by determining the power coefficient and the power collected by the turbine to select the wind turbine adapted to a well characterized site.
