Abstract
Abstract An apparatus for separating liquid from a liquid/gas mixture by establishing a laminar flow within a curved channel. Entrained liquid droplets, that have higher inertia than the gas, follow a trajectory, deviate from the gas flow lines, and impinge on the wall. The liquid droplets coalesce and migrate to the inner radius under the influence of shear from the secondary flow, where the liquid is collected and retained in an artery by capillary action. The liquid is then forced through bleed ports into the liquid drain line. The term liquid/gas mixtures is intended to include liquid/vapor mixtures as well.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
85 words
An apparatus for separating liquid from a liquid/gas or liquid/vapor mixture comprising: a curved main channel with an inlet into which flows the mixture, said curved channel forming a surface against which liquid droplets within the mixture impinge against; a collection artery for collecting droplets separated from the mixture; a plurality of bleed ports connected to said collection artery for removing the separated droplets from said channel; wherein, the liquid portion of the mixture is separated from the remainder of the mixture by said apparatus.
Claim 2
Independent Claim
85 words
An apparatus for separating liquid from a liquid/gas or liquid/vapor mixture comprising: a curved main channel with an inlet into which flows the mixture, said curved channel forming a surface against which liquid droplets within the mixture impinge against; a collection artery for collecting droplets separated from the mixture; a plurality of bleed ports connected to said collection artery for removing the separated droplets from said channel; wherein, the liquid portion of the mixture is separated from the remainder of the mixture by said apparatus.
Claim 3
Dependent Claim
30 words
An apparatus as claimed in claim 1, wherein, a liquid drain line is connected to said plurality of bleed ports for transporting the liquid droplets separately from said main channel.
Claim 4
Dependent Claim
40 words
An apparatus as claimed in claim 1, wherein, said main channel constructed in cross section as a teardrop shape having a substantially circular portion and a pointed portion, said pointed portion of said main channel acting as said collection artery.
Claim 5
Dependent Claim
79 words
An apparatus as claimed in claim 2, wherein, said main channel constructed in cross section in a substantially circular shape that is curved along the central axis of said main channel, said curved main channel comprising an inner radius and an outer radius; said liquid drain line is located against a wall of said main channel, said collection artery comprising two collection points at two intersection points of said liquid drain line with said wall of said main channel.
Claim 6
Dependent Claim
27 words
An apparatus as claimed in claim 4, wherein said liquid drain line is connected to said main channel wall at said inner radius of said main channel.
Claim 7
Dependent Claim
27 words
An apparatus as claimed in claim 1, wherein, said apparatus further comprises an additional fluid channel at least partially surrounding said main channel for effecting heat exchange.
Claim 8
Dependent Claim
25 words
An apparatus as claimed in claim 2, wherein, said drain line is at a lower pressure than said main channel to assist in liquid drainage.
Claim 9
Dependent Claim
17 words
An apparatus as claimed in claim 1, wherein, said main channel is formed in a spiral configuration.
Claim 10
Dependent Claim
17 words
An apparatus as claimed in claim 1, wherein, said main channel is formed in a coil configuration.
Claim 11
Dependent Claim
60 words
An apparatus as claimed in claim 1, wherein, said main channel having a construction in cross section that has a substantially circular portion that is curved along the central axis of said main channel, said curvature of said main channel defining an inner radius and an outer radius, said collection artery located at said inner radius of said main channel.
