Podgorny Institute of Mechanical Engineering Problems of the National Academy of Sciences of Ukraine popup.description2 Schematic solutions for the conversion of CHP power units to steam-gas technologies were developed. Substantiation of their efficiency under the condition of maximum use of existing equipment in the process of such modernization are carried out. Design and optimization of flow parts of turbomachines was carried out by modeling and identification of thermogas-dynamic and thermochemical processes, thermodynamic analysis and thermoeconomic optimization. The following fundamental and applied problems were solved during the research: - optimization of theoretical and real cycles of gas turbine and steam turbine units is performed; - circuit solutions for the reconstruction of gas power units of CHP are proposed; - a series of 3D CFD calculations was performed and a new flowing part of the high-pressure cylinder of the steam turbine T-110/120 was proposed; - the problem of identification of the mathematical model of functioning of the gas turbine unit GTE-60A at the nominal mode is solved4; - circuit solutions and methods of calculation of electrochemical power plant on the basis of high-temperature fuel cells are offered. The results of the research are planned to be implemented at the enterprises of the mechanical engineering industry and power plants of Ukraine and abroad.
