Steady-Adjoint Optimization of Tonal and Trailing-Edge Propeller Noise

This paper presents an efficient optimization framework for reducing tonal and turbulent boundary-layer trailing-edge noise (TE) of a subscale propeller operating in forward flight. The steady-state Reynolds-averaged Navier–Stokes solver is coupled with the Ffowcs Williams–Hawkings acoustic analogy to predict thickness...
