Box-Length Requirements for Simulation of Sound from Large Structures in Jets

Publication Summary

This study presented an estimate for the computational box length scale needed for an accurate estimate of the total acoustic power output emitted by a large scale structure in the form of a wave packet. The model shows that two different scales dominate the sound production: the source integral length scale for the low subsonic case and the plain source length scale for the supersonic case. Thus, the computational box length must be bigger than each length scale in its dominant region
