Study of aerodynamic characteristics of the model of a wind turbine with rotating cylinders

Abstract

The paper discusses problems of alternative energy sources uses, particularly wind energy utilization. The results of an experimental study of the aerodynamics of wind turbines using Magnus effect are considered. To carry out testing, a model of a three-blade wind turbine with rotating cylinders of various cross-sections was made. Aerodynamic testing of the wind turbine model at various airflow conditions was performed. Dependencies of drag force, tractive force and rotation frequency of the wind wheel on the flow rate at different yaw angles of the flow were found. It is shown that the use of rough-surfaced rotating cylinders of various cross-sections makes it possible to use an additional moving force resulting from the Magnus effect.
