In this paper, we investigate the performance of the seventh-order hybrid
cell-edge and cell-node dissipative compact scheme (HDCS-E8T7) on curvilinear mesh
for noise prediction in subsonic flow. In order to eliminate the errors due to surface
conservation law (SCL) is dissatisfied on curvilinear meshes, the symmetrical conservative
metric method (SCMM) is adopted to calculate the grid metric derivatives
for the HDCS-E8T7. For the simulation of turbulence flow which may have main responsibility
for the noise radiation, the new high-order implicit large eddy simulation
(HILES) based on the HDCS-E8T7 is employed. Three typical cases, i.e., scattering of
acoustic waves by multiple cylinder, sound radiated from a rod-airfoil and subsonic
jet noise from nozzle, are chosen to investigate the performance of the new scheme for
predicting aeroacoustic problem. The results of scattering of acoustic waves by multiple
cylinder indicate that the HDCS-E8T7 satisfying the SCL has high resolution for the
aeroacoustic prediction. The potential of the HDCS-E8T7 for aeroacoustic problems on
complex geometry is shown by the predicting sound radiated from a rod-airfoil configuration.
Moreover, the subsonic jet noise from nozzle has been successfully predicted
by the HDCS-E8T7.
