| Abstract(in English) | In this study, a numerical simulation of nonlinear sound wave propagation in the time domain is performed by the constrained interpolation profile (CIP) method. Two CIP formulations are made for two-dimensional nonlinear sound wave propagation : one is the standard formulation in which the nonlinear equation is divided into the advection term and the nonadvection one corresponding to the nonlinear term, and the other is the formulation based on the dependence of local sound speed on particle velocity. In the latter method, the nonlinear term is included in the local sound speed of the advection term, which can be directly solved by the CIP method. The numerical schemes are implemented into Graphics Processing Unit (GPU) for high performance computation. Some numerical demonstrations are performed for two-dimensional nonlinear sound propagation in air. The numerical results are compared with the analytical results. |
