The acoustic field of pipe generated by eccentric source in the liquid

In order to use the data measured by circumferential acoustic device (CAD), sector bound test (SBT) and acoustic image tool, the 2D acoustic field of pipe generated by eccentric source is studied numerically. A series of snapshots at different time instants and the waveforms at several positions are given. The results clearly exhibit all wave components and their propagation characteristics. Experimental results are given too.
