Abstract
In this paper we introduce new outlet boundary conditions to simulate 3D rotating flows within an interdisk cavity. The boundary conditions have been implemented in a multidomain pseudo-spectral algorithm and a quantitative method has been developped to qualify them. Numerical results show a reduction of about 50 % of the refracted wave amplitude compared to the convective boundary conditions that are commonly used.
