Abstract

The sounding mechanism in air-reed instruments is investigated based on the computational fluid dynamics. While previous studies have assumed a sound source based on acoustic theory, the authors attempt in the present study to elucidate exactly the source of sound as an essential factor defining the timbre of musical instruments. To deal with the large computational grids required to capture minute changes in pressure, the Hitachi SR 8000 massively parallel supercomputer is employed for computation. The computational results are consistent with Brown's experimental equation, and new frequency component revealed only in this three-dimensional analysis is identified, attributed to the harmonics of the air jet.
