Direct FVM Simulation for Sound Propagation in an Ideal Wedge

الملخص EN

The sound propagation in a wedge-shaped waveguide with perfectly reflecting boundaries is one of the few range-dependent problems with an analytical solution.

This provides a benchmark for the theoretical and computational studies on the simulation of ocean acoustic applications.

We present a direct finite volume method (FVM) simulation for the ideal wedge problem, and both time and frequency domain results are analyzed.

We also study the broadband problem with large-scale parallel simulations.

The results presented in this paper validate the accuracy of the numerical techniques and show that the direct FVM simulation could be applied to large-scale complex acoustic applications with a high performance computing platform.
