Large Eddy Simulation for Aeroacoustics Analysis of a Deployed High-Lift Wing
Description | We have demonstrated that advanced engineering computational methods can now be used to capture the noise generation and transmission from the initial fan blades, right through a large jet engine by-pass duct, and out into the exhaust including interaction with a deployed high-lift wing flap. In particular the computer simulations have been shown to capture the various known, and newly identified, noise sources and new mathematical modelling descriptions developed for these. A good comparison with available experimental data has been achieved and the Lattice Boltzmann Method has been shown to provide equivalent results to Navier-Stokes simulations at much reduced computation cost, using the XFlow commercial code. |
Exploitation Route | The work allows a better understanding of the overall noise generation mechanisms for latest generation very large by-pass ratio aeroengines, and so can help facilitate the introduction of control techniques required to meet 2020 noise emission targets. It shows that such high-fidelity computational aeroacoustics analysis can now been performed for whole engine configurations and so help minimise propulsion system integration penalties for aircraft operations. For the future such methods can now be used with some confidence to develop novel aircraft/engine configurations and technologies that will be needed to meet more stringent 2050 emissions targets. |
