| Research Abstract |
In this research, data-mining techniques are applied to complex aeroacoustic fields, and it shows that these techniques can be used for the automatic characterization of acoustic waves and the exploration of sound sources. Specifically, these techniques are applied to aeroacoustic waves from a supersonic jet impinging on an inclined flat plate, and its source position and characteristics are clarified. These insights are utilized for the prediction model of aeroacoustic waves form rocket plumes.
