Konovalov D. Development of scientific and technical bases of aerothermopressor technologies use power plants secondary heat

The dissertation is devoted to the solution of the scientific and applied problem of scientific and technical bases development of aerothermopressor technologies using for secondary heat of power plants for working fluid cooling. Based on the presented complex of physical and mathematical models of use processes of power plants secondary heat in an aerothermopressor the methodology of such systems rational design, which considers incomplete evaporation of the injected liquid and influence of dispersion was developed. The concept of increasing the power plants efficiency based on aerothermopressor technologies was also developed, which provides efficient high-dispersed spraying of liquid for after isotherming of the compression process in compressors with an additional increase in total air pressure. Based on numerical calculations and experimental research the regularities and characteristics of processes in aerothermopressor at air cooling as a working fluid component and high-utilization of products energy of power plants combustion were established, specifically influence of incomplete evaporation in the aerothermopressor on high-dispersion efficiency. Therefore, increase the capacity and power plant efficiency. Based on this, the principles of aerothermopressor application for intercooling of gas turbine air, charge air cooling of internal combustion engines, as well as for heat-using systems based on ejector refrigeration machines are determined
