Construction of acoustic model and simulation of sound absorption of aero-engine composite acoustic liner

Construction of acoustic model and simulation of sound absorption of aero-engine composite acoustic liner

Acoustic liner is an important component to reduce engine noise. In this work, the modal sound source characteristics of the pipeline under different flow fields were calculated and used as the input boundary for the background flow field calculation and sound propagation calculation of the Actran s...
