Subject of research - the cooling of gas turbine rotors. The purpose of the project - to create a method of calculating the centrifugal pressure in the rotor cavities of gas turbines and use this method in conjunction with the method of calculation of hydraulic networks to create an effective system cooling of the rotor and blades of the gas turbine of 190 MW capacity. Methods of research are based on the fundamentals of the theory of heat transfer, fluid dynamics, numerical methods for heat conduction and convection heat transfer, calculation methods branched hydraulic networks. In particular, for the calculation of hydraulic networks cooling systems use a method based on graph theory; for calculation of the thermal state of the turbine rotor - the finite element method; for the solution of ordinary differential equations for flow rotation in the cavities of the rotor of the turbine - Runge-Kutta method. Numerical simulation of flow in the inner cavities of the rotors, established method of calculation of the centrifugal pressure, taking into account the shape of the cavity, the direction of flow, the speed of rotation of the rotor, the parameters of the coolant. The calculations of the cooling of the rotor and the rotor blade of the first stage of a gas turbine capacity of 190 MW gas turbines, based on which they offer effective cooling system.
