Abstract
A noise abatement device and method to direct flow in a predetermined manner to substantially reduce the aerodynamic noise and structural vibrations produced by steam entering an air-cooled condenser in a power generating system. The interactive flow between the spargers that produces the aerodynamic noise and structural vibrations is largely eliminated by prohibiting fluid flow through selected flow regions within the spargers. The spargers include a stack of disks with fluid passageways. The fluid passageways are interrupted with continuous and undivided regions of the sparger to direct radial flow away from adjacent spargers, substantially eliminating the interactive flow.
