The primary sources of noise in a modern high bypass ratio turbofan
engine are associated with the jet exhaust and the fan. The
calculation of the noise radiated by the engine presents many
challenges. In this seminar, these challenges and strategies to
overcome them are discussed. The particular focus will be on the
simulation of the turbulent jet flow and the noise it radiates. The
limitations of computational resources and the need for relatively
rapid predictions dictate the choice of the numerical approach. The
possible approaches and the reasons for their selection will be
discussed. Examples will be given of benchmark tests of these methods
as well as jet noise predictions for jets of different exit geometry.
Some discussion of the prediction of the radiation of fan exhaust
noise will also be given. The reasons for the selection of the
numerical approaches and example solutions for this problem will also
be provided.
