摘要：

We design a perfectly matched layer for the advection-diffusion equation. We show that the reflection coefficient is exponentially small with respect to the damping parameter and the width of the PML and independently of the advection and of the viscosity parameters. Numerical tests assess the efficiency of the approach. (C) 2010 Academie des sciences. Published by Elsevier Masson SAS. All rights reserved.
