Abstract: One step numerical simulations of aeroacoustic problems were studied with the help of nonreflecting boundary conditions. A DNS scheme based on finite difference method is used to solve the governing equations. The widely use Navier strokes characteristics based boundary conditions for unsteady flows has been proven accurate, only if the wave incidence is normal to the computational boundary. The calculation of a backward facing step flow in a duct is easy to obtain good results for the aerodynamic flowfield. This study reports on a comparison of different nonreflecting boundary schemes for one step simulation of duct aeroacoustics.
