description: This thesis focuses on studying the influence of various geometrical configurations of the outlet sections of the cooling channels of the nozzle blade in a gas turbine unit (GTU). The research aims to: 1. Examine the methods of air cooling for gas turbine blades. 2. Simulate the thermal state and film cooling efficiency on the surface of theÂ blades in the flow field. 3. Identify the optimal geometry of the cooling channel for efficient nozzle blade cooling. A comprehensive thermal analysis of the first stage cooled nozzle blades of a high-temperature turbine was performed using computational fluid dynamics (CFD) methods to determine the thermal states of all flow surfaces. The study also analyzed the reduction in the metal temperature of the nozzle blade based on the geometry of the cooling channels.
