Subject of investigation - the intensification of heat transfer processes in gas turbine cycles and patterns and parameters for the gas mixtures and liquid coolants. The aim of the project - improving performance heat transfer equipment, development of methods and conditions of their achievements to ensure that the technical level of the perspective generations of gas turbine plants of the Energy Strategy of Ukraine. Has been further developed the concept of modernization of gas-turbine drive gas compressor plants of complex cycles in terms of creating energy efficient and energy saving equipment, comprising the main directions of improving the characteristics of heat exchangers - regenerators, exhaust gas boilers, heater-utilizeres of air-recovery turbine plants to the achievement of the following factors: the thermal efficiency of 0.8. .. 0.85, total losses of pressure 4 ... 6%, the resource - at least 100,000 hours and mass up to 100 tons. For the first time, in accordance with similarity theory, derived the system of dimensionless parameters, consisting of mass, volume, functional efficiency and resource, which allows for a comparative analysis of heat transfer equipment in the various turbine plants. First proved the effectiveness of comprehensive improvement of heat transfer in regenerators and boilers exhaust gas turbine plants by controlling the boundary layer at the outer coolant flow and internal flow fluids to reduce the thermal resistance of convective heat transfer from hot and cold side heat-transfer agents in reducing the thermal resistance of the hydrodynamic and thermal boundary layers, which in Reynolds analogy factor index is 0.95 ... 1.1 under the same pressure drop as compared with smooth tubes. For the first time in evaluating the effectiveness of the proposed ways to improve the heat transfer is simulated for multilayered banks, the results of which revealed that the stabilization of heat transfer for external flow from one to eight rows ends on the fifth or sixth row, causing the error in determining the averaging of the heat transfer coefficient can be up to 10 %. Has been further developed a method of designing new types of regenerators industrial gas turbines with minimization of weight and size parameters by taking into account dependencies in the definition of heat transfer coefficients and hydrodynamic resistance in the external flow around staggered elliptic tube longitudinal and transverse steps of their location. The obtained results of scientific methods to improve heat transfer to the coolant on thermophysical properties of the different state of aggregation and contribute to the development of the theory of intensification of heat transfer in heat exchangers such as "gas" - "gas" and "gas" - "liquid."
