Abstract

We report on simulation and analysis efforts to understand and predict the high amplitude aeroacoustic resonances (> 160dB) that have been observed in Arnold Engineering Development Center (AEDC) jet engine test cells. The basic configuration of these cells is a jet exhausting through a cylindrical duct. We summarize progress in developing analytical tools to diagnose the energetics of the resonating acoustic modes, direct numerical simulations to Investigate the phenomenology of the resonance in model geometries, and full-scale simulation tools to anticipate resonances.
