Low-gravity water capture device with water stabilization
An apparatus to separate water droplets from an air stream. The apparatus includes an elongated tube, a reservoir, and a helix structure. The elongated tube has a first end, a second end, a longitudinal axis, an inner surface, an inlet opening at the first end of the elongated tube, the inlet opening arranged to accept the air stream tangentially relative to the longitudinal axis, and an outlet opening at the second end of the elongated tube. The reservoir is positioned at a second end of the elongated tube. The helix structure is positioned within the elongated tube and includes an upper surface, a lower surface arranged opposite the upper surface, an outer edge, and a variable pitch along a length of the elongated tube, the variable pitch providing a variable interior angle between an inner wall of the elongated tube and the upper surface of the helix structure.
1. An apparatus to separate liquid droplets from a gas stream, the apparatus comprising:
an elongated outer housing comprising an inlet opening of the elongated outer housing, and an outlet opening of the elongated housing, wherein the inlet opening is arranged to accept the gas stream;
wherein the inlet opening feeds the gas stream into a channel that includes a helix structure, the helix structure comprising a variable pitch and variable interior corner angle configured to separate liquid from the gas stream;
and wherein the channel feeds the gas stream into a first flow path and a second flow path structurally separated from the first flow path, and wherein liquid separated from the gas stream flows into the second flow path;
and wherein the first flow path and the second flow path merge at the second end of the housing, wherein the second flow path includes vanes positioned in a reservoir, and wherein the vanes are configured to direct liquid droplets collected on surfaces of the helix structure.
2. The apparatus of claim 1 , wherein the reservoir collects liquid separated from the gas stream.
3. The apparatus of claim 2 , wherein the reservoir includes an inlet portion having a first cross-sectional area, and a collection portion having a second cross-sectional area that is greater than the first cross-sectional area.
4. The apparatus of claim 1 , wherein the helix structure extends into the second flow path.
5. The apparatus of claim 4 , wherein the helix structure extends into the reservoir.
6. The apparatus of claim 1 , wherein the second flow path includes vanes positioned in the reservoir and configured to direct liquid droplets collected on surfaces of the helix structure.
7. The apparatus of claim 1 , wherein the helix structure at least partially defines a variable interior corner angle configured to separate liquid from the gas stream.
8. The apparatus of claim 1 , wherein the apparatus includes at least one vane that guides the liquid droplets from the gas stream to the helix structure.

wherein the inlet opening feeds the gas stream into a channel that includes a helix structure, the helix structure comprising a variable pitch and variable interior corner angle configured to separate liquid from the gas stream;
and wherein the channel feeds the gas stream into a first flow path and a second flow path structurally separated from the first flow path, and wherein liquid separated from the gas stream flows into the second flow path;
and wherein the first flow path and the second flow path merge at the second end of the housing, wherein the second flow path includes a reservoir that collects liquid separated from the gas stream and wherein the helix structure extends into the second flow path and the reservoir.
13. The apparatus of claim 12 , wherein the second flow path is at least partially external to the outer housing.
14. The apparatus of claim 12 , wherein the second flow path includes vanes positioned in the reservoir and configured to direct liquid droplets collected on surfaces of the helix structure.
15. The apparatus of claim 12 , wherein the helix structure at least partially defines a variable interior corner angle configured to separate liquid from the gas stream.
16. The apparatus of claim 12 , wherein the reservoir includes an inlet portion having a first cross-sectional area, and a collection portion having a second cross-sectional area that is greater than the first cross-sectional area.
17. The apparatus of claim 12 , wherein the apparatus includes at least one vane that guides the liquid droplets from the gas stream to the helix structure.
