The aviation industry is required to produce and operate an environmentally friendly aircraft. One of challenging issues is the noise reduction. One solution is an acoustic liner.It is required to investigate the influence of flow to acoustic liner. In this study, we performed aeroacoustics analysis of simplified acoustic liner model consist of three resonators using Cartesian-mesh CFD. Three incident sound pressure is set to investigate the influence of the sound power to acoustic liner. According to the computational result, high incident sound pressure affects the flows in the resonator.
