| 中文摘要 | A direct numerical simulation of a turbulent mixing layer with the Reynolds number 500 and the convective Mach number 0.6 is performed and the results obtained are used to study the turbulent flow field and its generated noise. In the present simulation, the numerical techniques of absorbing buffer zones, artificial convection velocity and spatial filtering are used to achieve nonreflecting boundary conditions. The self-similarity is used to validate the present numerical simulations. The large-scale coherent structures are plotted together with the acoustic waves, which demonstrates the directivity of acoustic waves. The Lighthill’s source and space-time correlations are further investigated. The main contributions to mixing noise are identified in terms of large-scale coherent structures, Lighthill’s source and space-time correlations. |
