A methodology to study numerically the aeroacoustic response of low Mach number confined flows to acoustic excitations is presented. The approach combines incompressible flow computations, vortexsound theory, and system identification techniques, and is applied here to study the behavior of a two-dimensional laminar flow through a -joint. Comparison with experimental results available in literature shows that the computed source models capture the main physical mechanisms of the sound production in the shear layer of the -joint.
