摘要	This paper focuses on the radiation noise of a rod-airfoil configuration based on a high-order cellcentered finite difference method (CCFDM) and Ffowcs Williams-Hawkings (FW-H) acoustic analogy. To reduce numerical dissipation and dispersion, a class of optimized compact schemes is firstly proposed and then validated with benchmark cases from computational aeroacoustic workshops. For turbulence, the delayed detached eddy simulation (DDES) with Spalart-Allmaras model is adopted and is validated through a canonical periodic hill problem. For the far-field radiated acoustics, the FW-H acoustic analogy is utilized with validation of laminar flow past NACA0012. Finally, a rod-airfoil configuration is investigated. The results show reasonable agreement with the experimental data in terms of both near-field aerodynamics and far-field acoustics. The interaction between the upstream turbulence wake from the rod and the downstream airfoil is evidenced to be the dominant contributor to the far-field noise. (C) 2020 Elsevier Masson SAS.
