The purpose of the GDR is to increase the efficiency and reliability of the components of the flowing parts of steam and gas turbines, based on the use of an integrated approach to experimental research, calculations and optimization of the turbomachine flow parts. Methods of research - based on the classical aerodynamic experiment, conducted according to the generally accepted method, on the fundamental principles of gas dynamics, the theory of turbomachines, numerical mathematical methods. Theoretical and practical results - an analysis of experimental research methods, current flow calculation methods and features of existing structures of turbomachinery transient and output nozzles; A method for calculating centrifugal pressure in the disk cavities of gas turbines and compressors, taking into account their geometric characteristics, has been developed; A mathematical model is developed, which is based on the joint solution of the system of equations of thermogasdynamic processes in the flowing parts of cylinders of high, medium and low pressures simultaneously with the system of equations describing processes of water vapor flow through a system of steam distribution, which includes a network of steam pipes, locking and throttle valves , segments of the nozzle grid, working grid of the regulating power and a soothing camera. Scientific novelty - the first developed mathematical model, which is based on the joint solution of the system of equations of thermogasdynamic processes in the flow parts for the complex multicriteria optimization of the flow part of a powerful steam turbine. Introduced at the Department of turbine construction NTU "KhPI", JSC "Turboatom". The scope of research and design of turbine-building enterprises and enterprises of power engineering.
