Liner optimization using a hybrid finite element method

Lafronza, L., Song, W., McAlpine, A., Astley, R.J. and Keane, A.J. (2005) Liner optimization using a hybrid finite element method At 6th European Conference on Turbomachinery, Fluid Dynamics and Thermodynamics. 07 - 11 Mar 2005. , pp. 1085-1095.

Record type: Conference or Workshop Item (Paper)


This paper makes use of a novel finite element method for aeroacoustics analysis to examine and optimise the design of liners for aeroengine inlets. The finite element approximation used is very efficient since it allows the treatment of non-axisymmetric nacelles by combining a standard biquadratic approximation in the axial and radial directions, with a spectral representation in the circumferential direction. Results from the code are used in a multi-fidelity optimization approach which is based on response surface and formal design of experiment methods. The design optimization also makes use of Grid computing technology to allow efficient use of computational resources and effective managment of the analysis results. The use of these various techniques in combination allows for significant improvements to liner designs with realistic geometries at modest computational cost.
