Sounding mechanism is numerically analyzed to elucidate physical processes in air-reed instruments. As an example, compressible large-eddy simulations (LES) are performed on both two and three dimensional ocarina. Since, among various acoustic instruments, ocarina is known as a combined system consisting of an edge-tone and a Helmholtz resonator, our analysis is mainly devoted to the resonant dynamics in the cavity. We focused on oscillation frequencies when we blow the instruments with various velocities.Comment: 8 pages, presented in Open Source CFD International Conference 200
