2. Design optimisation of aeroengine compressor blades
Abstract : Optimisation of multistage axial compressors is a time-demanding challenge in large need of effective methods. Traditionally, the design has been based on "trial-and-error" procedures, which count on the skills and experience of the designer to suggest redesigns that are likely to yield improvements.

3. Aerodynamics of an Aeroengine Intermediate Compressor Duct: Effects from an Integrated Bleed System
Abstract : With the successful development of high-bypass-ratio turbofan engines, major aerodynamic components have been optimized and continuous efficiency improvements are getting harder to maintain. Therefore, to meet the requirements of lower emission of greenhouse gases, auxiliary modules such as intermediate ducts are receiving increasing interest. READ MORE

4. A Linearized Navier-Stokes Equations Methodology for Aeroacoustic and Thermoacoustic Simulations
Abstract : Aeroengine noise is one of the dominating noise sources in today’s aircraft. Reduction of the aeroengine noise is related to multiphysics phenomena, and that is subject to different mechanisms, e.g., the coupling between turbulence, flame and sound waves. READ MORE

5. Swirl stabilized premixed flame analysis using of LES and POD
Abstract : For environmental and human health reasons, the regulations on the emissions from combustion devices are getting more and more strict. In particular, it is important to abate the emission of pollutants deriving from combustion in gas turbines. A solution is the use of swirl stabilized, lean premixed combustion. READ MORE
