Results of numerical simulation are also presented. Verticals walls of the closed channel have different temperature instead of horizontal walls which is heat-insulated. Velocity fields features, their isolines, fields of pressure and temperature were studied in detail within the framework of Boussinesq approximation depending of Prandtl and Grashof numbers. Nonstationary three-dimensional turbulent flow of incompressible fluid over a rectangular two-dimensional obstacle in the boundary layer has been studied numerically using hybrid LES/URANS-approach, near-wall models and finite difference method. Coherent structures of different configuration were found. Nonstationary phenomenological theory of vertical geothermal systems has been developed. This system considered as thermodynamic highly nonequilibrium hydrothermaodynamic system. Fundamental energetic characteristics of the this theory which completely determine qualitative and quantitative properties of extraction energy are introduced. New technological approaches about construction of optimal geothermal systems were proposed based on the developed theory. Materials about optimization of Aerodynamic Complex of Interdisciplinary Research (ACIR) are also presented. Design, development and commissioning of additional aerodynamic facility complementing ACIR have been made. Product Description popup.authors Бруяцький Є.В. Виноградский П. М. Костін О.Г.
