Abstract
Abstract A high capacity vane (10) is disclosed which incorporates a series of members (16, 18) extending at predetermined angles relative to the direction of flow of a liquid bearing gas. Each of the members includes an upstream cavity (20) and a downstream (21) which communicate with the flow through longitudinal slots (24, 28). The flow interaction with the slots and cavities provide sufficient separation of the liquid from the gas flow.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
162 words
A high capacity vane for a moisture separator to separate moisture from air flowing in an air flow direction, comprising: a first member extending at a predetermined angle relative to the direction of air flow from a leading edge to a trailing edge, said first member having an upstream cavity formed therein and a downstream cavity formed therein; a second member extending from the trailing edge of the first member at a second predetermined angle relative to the direction of air flow, said second member having an upstream cavity formed therein, and a downstream cavity formed therein; and a first side of said first member having first and second longitudinal slots formed therein perpendicular the direction of air flow, each of said slots opening into one of said cavities, a second side of said second member having first and second slots formed therein extending perpendicular the direction of air flow, each of said slots opening into a cavity in said second member.
Claim 2
Dependent Claim
162 words
A high capacity vane for a moisture separator to separate moisture from air flowing in an air flow direction, comprising: a first member extending at a predetermined angle relative to the direction of air flow from a leading edge to a trailing edge, said first member having an upstream cavity formed therein and a downstream cavity formed therein; a second member extending from the trailing edge of the first member at a second predetermined angle relative to the direction of air flow, said second member having an upstream cavity formed therein, and a downstream cavity formed therein; and a first side of said first member having first and second longitudinal slots formed therein perpendicular the direction of air flow, each of said slots opening into one of said cavities, a second side of said second member having first and second slots formed therein extending perpendicular the direction of air flow, each of said slots opening into a cavity in said second member.
Claim 3
Dependent Claim
33 words
The high capacity vane of claim 1 wherein a plurality of vanes are positioned at predetermined separations along a direction perpendicular the direction of air flow to separate moisture from the air flow.
Claim 4
Dependent Claim
51 words
The high capacity vane of claim 1 wherein the flow contracts as it passes through the vanes, the contraction of the flow necessary to pass through the vane being less than 33 percent, while still maintaining tortuosity to separate droplets as small as ten microns in diameter with 95 percent efficiency.
Claim 5
Dependent Claim
55 words
The high capacity vane of claim 1 having a vane wavelength and a peak-to-peak amplitude, said upstream and downstream cavities in each of said first and second members each having a transverse thickness, the transverse thickness of the cavities being less than 1/45 of the vane wavelength and less the 1/14 of the peak-to-peak amplitude.
