Appl. No.:

10/387145

Assignee:

Fisher Controls International LLC - St. Louis MO

International Classification:

F01K 13/02

US Classification:

60646, 239431, 366107

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.

Abstract:

A system, method, and computer program for storing a polygonal topology, comprising representing a primitive with a plurality of vertices, internal half-edges and external half-edges; and storing said plurality of vertices in a vertex array and said plurality of external half-edges in a half-edge array, wherein said arrays are indexed and parallel to one another; whereby said primitive is re-created from said parallel array with said internal half-edges that are implicit from a primitive structure and appropriate means and computer-readable instructions.
