Abstract
A case study in the application of computational aeroacoustics in the prediction of flow noise from a subsonic jet generated at the tailpipe of a straight pipe. The simulation is completed using a hybrid approach. The results from a Large Eddy Simulation completed using are used to formulate acoustic sources. These acoustic sources are formulated using Lighthill's analogy and then mapped onto an acoustic finite element mesh using the tools built into the acoustic FEM software Actran. The total predicted sound power of the sources inside the pipe and the turbulent jet region are then validated to completed acoustic measurement using the University of Kentucky's muffler flow test rig.
