The aim of the research - development of methods and calculation programs of aerodynamics and acoustic processes during flow around of horizontal-axis wind turbines. Research methods - numerical integration of differential equations in ordinary and partial derivatives, the Navier-Stokes equations, the wave equation and the Helmholtz equation. The results of the development of complex method and methodical software for calculation of acoustic and aerodynamic processes in the flow of horizontal-axis wind turbines are presented. As the initial mathematical models full three-dimensional unsteady Navier-Stokes equations, wave equation, Helmholtz equation were used. In a numerical algorithm the finite volume method and the boundary element method were applied. The algorithms of discretization of the computational area and visualization of flow field were developed. The results of calculation of aerodynamic performances of horizontal-axis wind turbine, the noise of wind turbine at different wind speeds, sound spectrum, sound pressure levels at different distances from the rotor are presented. Practical recommendations for the design and placement of wind turbines are given. Industry - wind energy. Product Description popup.authors Алексеєнко С.В. Алхімов О.В. Горбенко Є.В. Сокол Г.І.
