A Low Frequency Model for Acoustic Propagation in a 2D Flow Duct: Numerical Computation
Published online by Cambridge University Press: 20 August 2015
Abstract
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.
