1. 1. Analysis of the Performance of Different V2F Turbulence Models in a Stator Vane Passage Flow

   Författare :Andreas Sveningsson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; heat transfer; RANS; realizability; V2F; stator flow;

   Sammanfattning : When designing the cooling system of modern gas turbines it is important to be able to predict the heat transfer from the hot gas to the walls surrounding the gas path. One flow feature making this rather complicated is the presence of secondary, three-dimensional flow structures, often referred to as horse shoe vortices, which greatly enhance the rate of heat transfer to the endwall, especially in the leading edge region.

3. 2. Turbulence Transport Modelling in Gas Turbine Related Applications

   Författare :Andreas Sveningsson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; RANS; secondary flow; realizability; V2F; transition;

   Sammanfattning : Computational fluid dynamics is a cornerstone in gas turbine engine design. It is used to optimize shapes of turbine and compressor airfoils, to predict heat transfer to gas turbine hot parts, to reduce the amount of pollutants that form when fuel is burnt, to reduce gas turbine noise and so on.
