Abstract
Jet noise from nozzle is predicted by seventh-order hybrid cell-edge and cell-node dissipative compact scheme (HDCS-E8T7). Turbulent flow, which has the main responsibility for the noise radiation, is simulated by a new high-order implicit large eddy simulation (HILES) based on the HDCS-E8T7. The conception of HILES is similar to that of monotone integrated LES (MILES), i.e., truncation error of the discretization scheme itself is employed to model the effects of unresolved scales. The Mach number in this case is 0.75 and the jet Reynolds number is . Sound pressure levels (SPL) in far-field observer locations are evaluated by Ffowcs Williams-Hawkings (FW-H) integral method. Predicted near-field flow statistics and far-field SPL are both in good agreement with the corresponding experimental data.
