ABSTRACT

In the context of designing a new air-gun with reduced high-frequency emissions, we developed computational fluid dynamics models that provide new insight into the dynamic behavior of air-guns. We combined these simulations with video images and high-fidelity acoustic measurements from physical tests to investigate the physical mechanisms contributing to the air-gun signature. We considered the dynamic output in the time domain, and the energy components in the frequency domain.
