Abstract

Abstract

In order to predict the engine intake noise accurately, transient analysis is used in aero-acoustics calculations of intake manifold flow, and the acoustics field distribution is simulated in acoustics software. Establish a one-dimensional engine model which is calibrated by experimental data to output reliable pressure and velocity results for flow field calculation. Two turbulence models, the large eddy simulation (LES) and detached eddy simulation (DES) methods are used separately to simulate the flow field in the manifold accurately. The aerodynamics noise is calculated by acoustic FEM method using surface pressure distribution. Comparisons between two algorithms indicate that DES can get results of similar accuracy with LES while DES using less time. The results are compared with NVH test data and the accuracy of simulation method is verified. The spectrum analysis between simulation results and pressure boundary in frequency domain make the design of vacuum filter and intake manifold more specific.
