DESCRIPTION: Ryoya Tabata --- Coupled Van der Pol oscillators are often used for the studying of synchronization mechanism among flue organ pipes. However, recent studies have suggested that the effect of near-field interaction between the air-jet motion and the acoustic field plays an important role in the mechanism of synchronization. In this study, we focus on the synchronization between an air-jet instrument and external sound source. We numerically explore the synchronization mechanism using a finite-difference lattice Boltzmann method (FDLBM) as a direct aeroacoustic simulation scheme in two dimensions. We succeed in reproducing the frequency-locking phenomenon between the monopole sound source and air-jet instrument in the stationary state. Numerical simulations are conducted on a GPU cluster to explore the large parameter space. Transient behavior towards the frequency-locking phenomenon was observed, and the results demonstrate that the external sound source strongly affects the air-jet oscillation and the phase relationship of the sound pressure inside the resonator.\n
