Numerical simulation of dynamics of vertical-axis wind turbines
Computing technology designed to perform parametric studies of various configurations of vertical-axis wind turbines based on aerodynamic calculations is presented. The analysis of 3D aerodynamic flows connecting with the functioning of models of wind turbines is carried out. Numerical simulation of a turbine with three twisted blades is performed by setting the wind speed and the angular speed of rotation of the turbine in a certain range of values, as well as by changing the geometric parameters (width, length and angle of inclination of the blade) that determine the design of the turbine. The quasi-stationary periodic modes of the turbine are studied, the conditions for optimal rotation are found, and estimates of torque pulsations are obtained depending on the specified parameters.
