Abstract

Issues of modernizing the current exhaust hoods of low-pressure sections for steam turbines manufactured by the Ural Turbine Works and designing new ones with the use of modern methods of computational fluid dynamics (ANSYS CFX) are considered. A flow in the exhaust hood is simulated numerically. Verification of obtained data is performed. The use of the finite volume method allowed the three-dimensional flow in the exhaust hood of turbines of the T-100 series to be analyzed and a simple variant for improvement of its characteristics to be developed. The project data on the novel design of the exhaust hood for the T-125/150-12.8 turbine are given.
