The Department of Aeronautical and Automotive Engineering at Loughborough University has been active for 40 years in teaching and research in the area of gas-turbine propulsion systems. In 1991 the University Technology Centre (UTC) in Combustion Aerodynamics was formed, specialising in both experimental and computational methods research on all aspects of combustion system aerodynamics. Such flows are often strongly influenced by the upstream compressor flow whilst also being subjected to effects such as strong diffusion, streamline curvature and high swirl. Experience with these types of flows has therefore led to aerodynamic related work being conducted in other areas of a gas turbine where such effects are present. This includes by-pass ducts, axial and swirling compressor transition duct flows, the design of ducting systems for inter-cooled engines etc.
LOUGH undertakes experimental measurements and numerical predictions of the aerodynamic flows within the annular S-shaped transition ducts used to connect the compressor spools.
