2. 1. Engine Optimized Turbine Design

   Author : Nicholas Anton; Anders Christiansen-Erlandsson; Magnus Genrup; Marc Gugau; KTH; []
   Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Turbocharger; Heavy-duty; Turbine; Axial; Radial; Machine Design; Maskinkonstruktion;

   Abstract : The focus on our environment has never been as great as it is today. The impact of global warming and emissions from combustion processes become increasingly more evident with growing concerns among the world’s inhabitants. The consequences of extreme weather events, rising sea levels, urban air quality, etc. READ MORE

4. 2. Some Aspects of Gas Turbine Fuel Preparation and Turbomachinery Response to LCV Fuels

   Author : Pontus Eriksson; Kraftverksteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; PDA; LDA; PIV; atomization; spray; off-design; biogas; combustor; biofuel; turbine; Gas turbine; compressor;

   Abstract : This thesis gives some background information on environmental issues as the scientific community at large currently sees it. It tries to relate the plethora of current combustion technologies which may be used in gas turbines to those issues. Some basic principles on combustion design are given. READ MORE

5. 3. Design of an Experimental Facility for Investi- gating the Flow in a Low Pressure Turbine Exit Structure

   Author : Borja Rojo; Chalmers University of Technology; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Turbine Rear Frame; Turbine Exhaust Case; Experimental; Exit Guide Vane; Engine Exit Structure; Aerodynamics; Outlet Guide Vane; Gas Turbine; Wind Tunnel; Heat transfer.; CFD; Turbine Rear Structure;

   Abstract : This report presents the design of a turbine facility for investigating the flow in the EES located at Chalmers University of Technology. The EES is the structure located downstream of the LPT in a jet engine. In this rig, in order to generate realistic inlet boundary conditions for the EES, an LPT stage is located upstream of the EES.

6. 4. Flow Control and Shape Optimization of Intermediate Turbine Ducts for Turbofan Engines

   Author : Fredrik Wallin; Chalmers University of Technology; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CFD; response surface methodology; intermediate turbine duct; vortex generators; turbine intermediate case; endwall contouring; turbine center frame; body-force model; shape optimization; mid-turbine frame; flow control;

   Abstract : Demands on improved efficiency, reduced emissions and lowered noise levels cause a strive towards high by-pass ratios of commercial turbofan engines. This results in an increased radial offset between the high- and low-pressure turbines. Thus the design of the intermediate turbine duct connecting the two turbines becomes more challenging.

7. 5. Aerothermal Study of Intermediate Turbine Ducts

   Author : Martin Johansson; Chalmers University of Technology; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Aerodynamics; Intermediate Turbine Duct; Gas Turbine; Heat Transfer; Experimental;

   Abstract : An intermediate turbine duct guides the flow from the smaller diameter high pressure turbine to the downstream larger diameter intermediate or low pressure turbine. It is typically equipped with a structural vane transferring loads for the core to the external parts, and supplies the core with necessary services such as oil and air. READ MORE
