This study proposes a numerical calculation method that simulates a nonlinear propagation of ultrasound beams, estimating the parametric sound field in the time domain. Basically, the method resorts to solving numerically and compactly the governing equations in a compressible viscous fluid. The simulation indicates a narrow sound beam which is a feature of the parametric array. Additionally, a self-silenced sound beam, which has a narrow truncated array length [C.M. Hedberg et al., Acoust. Phys. 56, 637--639 (2010)], is numerically simulated as a model application. The simulation shows a spatially restricted and very narrow difference frequency sound similar to their experiment. |
