Purpose of study - to develop the theoretical foundations of comprehensive energy saving system by creating a means to improve the efficiency of wind turbines on the territory of Ukraine and the creation of new low-cost alternative fuel due to the formation of heterogeneous systems such as gas-liquid and oil-brown coil-water compositions. Method of study - theoretical determination of aerodynamic characteristics of wind turbines optimally adapted to local wind conditions and the experimental measurements and computer processing of video-images of multi-components gas-liquid media which allows to obtain geometrical characteristics of dispersion objects. A new computer-oriented method of parameter optimization and design of wind turbines of various types and nominal capacity is worked out. Based on the qualitative and quantitative analysis of the wind potential of Ukraine recommendations was given to install wind turbines in different regions, including new areas, namely offshore zones and urban territories. The novelty of the research is that up to now wind turbines in such areas in Ukraine still are not used. A new method of building skeletal structure of image objects is suggested, which makes it less time-consuming process experimental study. The novelty is the construction of skeletal structures having one pixel thickness, which helps to identify images of real objects. A new method of segmentation is worked out that allows to analyze mixtures with large number of particles and high ceilings. The emulsion-suspension of brown coil with dispersed phase of MgCl2 solution in water is suggested. The presence of MgCl2, unlike the known suspensions, allows to link sulfur which is presented in coal and contributes to environmental safety. These materials are presented for use in Research Institute of Ferrous Metallurgy of NAS of Ukraine, Institute of Transport Systems and Technologies of NAS of Ukraine, Southern design office and other organizations.
