Direct FVM Simulation for Sound Propagation in an Ideal Wedge

Figure 7

The simulation for the single pulse source problem in the ideal wedge geometry. The bottom boundary is set rigid. The t value of each snapshot is listed in the subtitles of the figures. The small blue rings around the source in (g) and (h) are the secondary reflections on the edge of the source.
