The aim of the research - development of methods and programs for calculation of aero-hydrodynamic and acoustic processes, heat and mass transfer, performance evaluation of mechanical systems in mechanics and mechanical engineering. Research methods - methods of numerical integration of differential equations in ordinary and partial derivatives, the Navier-Stokes equations, the wave equation and the Helmholtz equation, experiment. Scientific and methodological support for mathematical modeling of aerohydromechanics and heat and mass transfer based on the Navier-Stokes equations is developed. Fundamental regularities, the structure and the specifics of the development of turbulent flows with separation and recirculation flow are revealed. The problem of aircraft icing as well as the problem of "barrier ice" during the operating de-icing system is considered. The problem of the development of free convection between two horizontal cylinders is considered. The examples of the solution of the problems of high-speed ground transport, aviation, rocket and space technology, mechanical engineering are presented. The effect of acoustic oscillations on the alive organisms is investigated. The design of multi-row bearings, providing uniform distribution of the external axial load between multiple multi-row bearings during their installation is shown. Constructive solutions are protected by patents for utility models. Geometric and algebraic models of the integral indicator of mechanical systems in defining the space are developed. Industry - aviation, transport, energy, engineering, agriculture. Product Description popup.authors Алексєєнко С.В. Дудніков В.С. Савчук Т.Л. Сокол Г.І. Хащина О.І. Хоріщенко О.А.
