采用时空滤波的方法将无界湍流分为辐射和非辐射两部分。然后，该结果用于澄清一些问题，包括识别此类流中声源的可能性。它也被用来研究一些最近的计算方法的有效性。
A space-time filtering approach is used to divide an unbounded turbulent flow into its radiating and non-radiating components. The result is then used to clarify a number of issues including the possibility of identifying the sources of the sound in such flows. It is also used to investigate the efficacy of some of the more recent computational approaches.
