A Fast Two-Dimensional Numerical Method for the Wake Simulation of a Vertical Axis Wind Turbine
Energies, 2020 In the array design of the vertical axis wind turbines (VAWT), the wake effect of the upstream VAWT on the downstream VAWT needs to be considered. In order to simulate the velocity distribution of a VAWT wake rapidly, a new two-dimensional numerical ...

Force Measurements on a VAWT Blade in Parked Conditions [PDF]
Energies, 2017 The forces on a turbine at extreme wind conditions when the turbine is parked is one of the most important design cases for the survivability of a turbine. In this work, the forces on a blade and its support arms have been measured on a 12 kW straight-bladed vertical axis wind turbine at an open site. Two cases are tested: one during electrical braking

Development and analysis of VAWT offgrid in ducting system
International Journal of Power Electronics and Drive Systems (IJPEDS), 2020 Horizontal Axis Wind Turbine (HAWT) had been widely used in Malaysia, however, research concluded that the power produced is still low which approximately 0.02% from the wind turbine input is. The average wind speed in Penang, Malaysia, is recorded between 1.0 m/s to 2.5 m/s whereby to produce 2.7 kW of power by HAWT, 12.0 m/s of average wind speed is ...
