要約
The computational challenges faced in conducting numerical simulations which capture the noise radiated by turbulent high-speed jets are summarized. Recent work of Bodony & Lele using LES for jet aeroacoustics is illustrated with focus on comparing near-field turbulence and far-field noise with available data for heated and unheated jets. The opportunity provided by high-fidelity simulations for studying and modeling aeroacoustic phenomena is stressed via model problems of sound generation, including a discussion of open problems. Recent progress in simulating and modeling broadband shock associated noise is highlighted.
