FIELD: wind power engineering.
SUBSTANCE: invention can be used for converting energy of air flows into electric energy. Proposed method includes passing of first on-coming air flow between two conversing and diverging aerodynamic surfaces in direction of flow to form zone of reduced pressure and transmitting of second air flow along pipeline from surrounding space into zone of reduced pressure. Converter is installed on way of second air flow. Space is made in zone of reduced pressure in, at least, one of aerodynamic surfaces to provide swirling of second air flow by wall of said space. Swirling of second air flow is formed tangentially in direction of passing of first on-coming air flow. Device contains two plates. Pipeline is designed to transmit second air flow. One end of pipeline is made open and it is connected with surrounding space, and other end is connected to outer surface of one of plates. Converter is installed in pipeline. AT least one of plates is provided with space to swirl second air flow. Space communicates with pipeline. Space is made orthogonally relative to direction of first on-coming air flow tangentially in direction of first on-coming air flow.
EFFECT: improved efficiency of energy conversion.
