abstract = {<p style="text-align: justify;">In this paper we study a low frequency model for acoustic propagation in a
2D flow duct. For some Mach profile flow, we are able to give a well-posedness theorem. Its proof relies on a quasi-explicit expression of the solution which provides us
an efficient numerical method. We give and comment numerical results for particular
linear, tangent and quadratic profiles. Finally, we give a numerical validation of our
asymptotic model.</p>},
