Analýza vlivu hustoty sítě a turbulence na numerické řešení proudění v turbínových stupních

Abstract

The diploma thesis deals with numerical modelling of turbulent steam flow by turbine stage and with density of meshes. The introductory part presents information about Doosan Škoda Power. The following chapters deal with a general description of steam turbines. The theoretical part describes the body's flow of surrounding fluid. Practical part deals with influence of computing meshes on results in 3D modelling of steam turbine. The final part of the practical part evaluates the impact of the computing meshes on the correct fitting of the turbulent model. In conclusion, an example of optimal parameters is given in order to capture significant effects of the streamlines field.
