THE EFFICIENCY OF THE DISCHARGE PIPE OF THE VORTEX WIND DEVICES WITH FLOW CONCENTRATOR

The object of the study is the exhaust pipe of a wind power plant (wind turbine) with a flow concentrator. The article aims to investigate the movement of air flow in a vortex wind turbine, the development of methods for calculating the wind turbine and determine its power in the presence of an exhaust pipe is presented. In the course of the work, a literary, patent review and analysis of mathematical methods, existing designs of wind turbines were carried out. As a result of researches, methods of calculation of a wind turbine and determination of its power at the set initial and boundary conditions are developed, the experimental stand was also made. Experiments were carried out taking into account the impact of the exhaust pipe on the parameters of the device. The novelty of the design lies in the flow concentrator with curved narrowing channels tangentially connected to the exhaust pipe.
