摘要:
A noise abatement system including at least one fluid circulation chamber to receive at least one flow of fluid; at least one vorticity-inducing component adjacent to the at least one fluid circulation chamber, the at least one vorticity-inducing component to redirect the at least one flow of fluid tangentially to an inside perimeter wall of the at least one fluid circulation chamber to create fluctuations in a flow and pressure of the fluid causing increased and variable vorticity within the at least one fluid circulation chamber; and at least one vorticity-interaction region in communication with the at least one vorticity-inducing component to attenuate acoustics caused by the at least one flow of fluid.
