Direct FVM Simulation for Sound Propagation in an Ideal Wedge

Figure 2

Comparison of the Fourier transform of the FVM result at 150-m depth and the section of the analytical solution to the Helmholtz equation at the same depth: (a) The section line; (b) TL result in a mesh of 127200 cells; (c) TL result in a mesh of 508800 cells; (d) TL result in a mesh of 2035200 cells. The continuous line indicates the analytical solution and the descrete dots indicate the result of the FVM simulation.
