摘要

The acoustic transmission is influenced by the presence of the flow of the medium through which the wave travels. There are many practical problems in which this effect must be taken into account. The present paper describes the boundary element modeling of the sound wave transmission iii moving medium. The boundary element formulation is first presented. Some examples of acoustic pipes are demonstrated. The case when the mean flow spatially presents is then considered. The field with partial mean flow is formulated by the combination of two boundary element domains.
