摘要
Abstract
The combination of Reynolds-averaged Navier-Stokes (RANS) and Non-linear Acoustics Solver (NLAS) solving lfow ifeld and acoustical ifeld respectively were applied to simulate the variation of noise for the ifxed refueling tube mounted on a certain type of aircraft. Acoustics pressure contour and noise spectra at different positions were given. Then, in the same position and condition, it compared the aircraft’s instaled refueling device with prototype’s acoustics pressure spectrum and noise. The results show that an increase of 3 dB in acoustics pressure level can be expected.关键词
