Abstract: The paper presents a technology of predicting the far-field acoustics based on calculating the surface integral in delayed. A specificity of the technology is that the far-field prediction is carried out simultaneously with the near-field computation. In doing so, we use all the available discrete data for the numerical integration and avoid the necessity to storage the huge amount of data on disks for the far-field estimation within the post-processing. The results on the test case simulating the acoustic monopole source in the subsonic flow are given.

Keywords: computational aeroacoustics, far field, Ffowcs–Williams–Hawkings method.
