1. 6. Method development for investigation of real effects on flow around vanes

   University essay from Mekanisk värmeteori och strömningslära

   Author : Jonathan Mårtensson; [2010]
   Keywords : Master s Thesis; Method Development; Real effects; Turbomachinery; Turbine Flow; Secondary Flow; ICEM; Block Mesh Topology; Tip Gap;

   Abstract : In the development of turbo machinery components it's desirable to not spend more time than necessary when setting up aero-thermal calculations to investigate uncertainties in the design. This report aims to describe general thoughts used in the development of an ICEM-mesh script and the possible configurations in the script file which enables the user to build mesh-grids with/without clearance gap at the hub and/or shroud for different blade geometries.

3. 7. Investigation of Losses Prediction Methods in 1D for Axial Gas Turbines

   University essay from Lunds universitet/Institutionen för energivetenskaper

   Author : Adrian Dahlquist N; [2009]
   Keywords : Loss models; axial gas turbines; Technology and Engineering;

   Abstract : A brief description of the physical flow phenomena in a blade row that creates losses in an axial gas turbine and correlations to estimate these losses in a mean line calculation are given. Investigation and comparison of the loss correlations for 1D mean line calculation between the in-house program (CTC) used at Siemens and loss correlations present in the open literature were made.
