Far – Field Noise Minimization Using an Adjoint Approach

In this paper, shape optimization is applied to a blunt trailing edge airfoil in an unsteady turbulent flow environment to minimize the radiated far-field noise using a novel hybrid Unsteady Reynolds-Averaged Navier-Stokes/Ffowcs Williams and Hawkings (URANS/FW-H) optimization algorithm. Airframegenerated noise is an important component of the total noise… CONTINUE READING
