Eric Lenormand Guest Posts: n/a	I m looking for informations on how an acoustic wave is damped when reflected on a turbulent boundary layer or through a turbulent flow. I m using an LES approach to model turbulence and I suspect the effect of turbulence on acoustic can be taken into account via an additional viscosity ... Am I right ? what viscosity should I add ? As any one any idea ? Thanks
