dc.description.abstract1The efficiency of gas turbine plants will be improved by cooling the cyclic air with an aerothermopressor. Constructive and technological factors affecting the aerothermopressor work were considered in this paper. CFD simulation and calculation of the water evaporation process in the evaporation chamber (working chamber) of the aerothermopressor was carried out. The Eulerian–Lagrangian approach was used to simulate the interaction of water droplets injected and airflow. The developed software was used in order to determine the characteristics of the aerothermopressor workflow. It is based on the methods of calculating thermogasdynamic compression and pressure losses due to the aerodynamic resistance of the two-phase flow in the aerothermopressor flow part. An empirical equation has been determined for calculating the optimal relative length of the aerothermopressor evaporation chamber depending on the initial droplet diameter at the inlet and the mass water concentration in the airflow. Analytical determination of the optimal relative length of the aerothermopressor evaporation chamber allows determining the length section of the evaporation chamber in order to obtain the maximum value of pressure increase, as a result of thermogasdynamic compression.uk_UA
