Broadband noise produced by the trailing-edge of a controlled di usion (CD) airfoil is directly simulated using a Lattice-Boltzmann method (PowerFlow) that resolves both the aerodynamic and acoustic eld around the airfoil. The proper DNS resolution is rst achieved in the vicinity of the airfoil on a quasi-2D slice of the mock-up. It is then extended to a 3D slice with a span of 12 % chord length. Two numerical setups of the anechoic openjet facility where both aerodynamic and acoustic data have… CONTINUE READING
