Abstract

Based on different sub-grid scale models, the Large Eddy Simulation (LES) is used to calculate the unsteady flow field and sound field of the Hyundai Simple Model (HSM). The experimental data of the internal monitoring points of the model are used to verify the simulation results. The results show that using the WMLES model can get more accurate results.
