Evaluation of Using No-Load Wind Wheels in a Flow Accelerator Body for Wind Power Plants with a Vertical Rotation

The article presents the research covering the long-term period of scientific and practical search for determining the most optimal confuser design for a wind power plant with a vertical rotation axis operating in the climate zones of small wind pressure. In the course of the work, tower-type installations with free blades in the body of the concentrator, hexagonal conical geometry with internal flow guide planes and a smooth-conical design with spiral chambers having a bounding bottom plane in the form of a spiral tray were presented. Analytical studies of the proposed installations are carried out, the dynamics of improving the system efficiency is estimated. Recommendations are given for the further development of scientific search within the framework of optimizing the initial design and the conditions for its operation. As a result of scientific and practical search, presented by mathematical modeling and laboratory tests, optimal geometries of wind flow concentrators with maximum acceleration coefficients were determined.
