2. 1. A Large-Scale Facility for Investigation of Intermediate Turbine Ducts: Design, Implementation and Initial Tests

   Author : Lars-Uno Axelsson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; diffuser; S-shaped duct; wind-tunnel design; gas turbine; turbofan; annular duct; Intermediate turbine duct;

   Abstract : Intermediate turbine ducts are used in modern multi-spool jet engines for guiding the flow from the high-pressure turbine to the low-pressure turbine. The demand for lighter, more efficient and more environmentally friendly aircraft engines requires the new jet engines to have higher by-pass ratios. READ MORE

4. 2. Experimental investigation of the flow field in an aggressive intermediate turbine duct

   Author : Lars-Uno Axelsson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; phase-resolved measurements; Intermediate turbine duct; flow visualization; vorticity dynamics; turbulence.; inter-turbine duct; hot-wire anemometry; experiment; 5-hole pressure probe;

   Abstract : Intermediate turbine ducts are used for connecting thehigh-pressure turbine to the low-pressure turbine in turbofan engines. In order to meet the demands for more efficient and environmentally friendly jet engines, future intermediate turbine ducts need to have larger radial off-sets without increasing their length.
