摘要：
A numerical study employing the Euler equations in a two-dimensional duct flows is presented. Thompson boundary conditions imposed at the inflow/outflow boundaries indicated bounded growth of absolute error with increasing angle of incidence of oblique acoustic disturbances, supporting the suitability of these boundary conditions for acoustic propagation and noise control problems.
