Abstract

The prediction of open or ducted rotor noise is a challenging problem as there are large difference in scales between the noise source near the rotor and the sound field. The sound field generated by an open rotor and that radiated by the same rotor placed inside a semi-infinite duct is simulated in DLR using a CAA multidomain method. The linearized Euler equations in cylindrical coordinates are used as governing equations in solving this problem. Both Tam's radiation and PML far field boundary conditions are used. A multidomain Cartesian grid system is used so that the number of grid points can be kept as a minimum. A combination of DRP and a specially optimized cell-centered high order differencing scheme is implemented in the area of two Cartesian grid interfaces.
