It has often been suggested that simulations of turbulent jets could provide the necessary sound source information for jet noise predictions via Lighthill’s acoustic analogy. Such an application of Lighthill’s equation is useful for two reasons. First, it provides a framework for identifying and modeling acoustic sources in a turbulent flow. Second, it may provide a less expensive means of computing the sound generated by turbulent flows because the flow equations would need to be computed only in the source region.
