3D numerický výpočet proudění v kompletním stupni experimentální parní turbíny T1MW a vliv geometrie proudových parametrů na účinnost.

Abstract

This master thesis deals with the modeling of the complete flow of steam turbine stage. The introduction presents a summary of information about the company Doosan Škoda Power. Next chapters are devoted to the distribution of steam turbines and their working process. Last chapter of theory deals with the theory of flow. The practical part is focused on the design geometry inverse model steam round blades in Autodesk Inventor, design of mesh in ANSYS Meshing and 3D numerical calculation of the turbine stage in ANSYS Fluent 13.0. It also studied the influence of friction steam of the rotor disk on the turbine efficiency. The results are graphically and numerically evaluated. These outputs are ultimately applied in the formula for calculating friction loss, where the only unknown is a constant that is selected in a specific interval and effort to of the master thesis is this constant to specify.
