Abstract: An apparatus and related methods to separate liquid from a liquid/gas mixture, particularly in a low gravity environment. The apparatus includes a chamber having a capillary channel around a perimeter of the chamber, a liquid/gas inlet to the chamber, a liquid outlet from the chamber, the liquid outlet being positioned at the perimeter of the chamber to remove liquid from the capillary channel, and a gas outlet from the chamber. The gas outlet is positioned in the chamber, away from the capillary channel, to remove gas from the chamber. The chamber is structured to be readily fabricated using traditional machining techniques or additive manufacturing techniques. The chamber may be fabricated from various materials, including, for example, polymers, metals, composites, and ceramics. The chamber may function as a heat exchanger so that the apparatus can remove condensable vapors from the gas in the mixture in addition to what is already liquid.

Abstract: An air-cooling system includes an evaporator adapted to cool an air and a reservoir for storing a liquid and providing the liquid to the evaporator. The air-cooling system also includes a pressure reducer system fluidly coupled to the evaporator and adapted to create a relatively low pressure inside the evaporator to facilitate a conversion of the liquid flowing through the evaporator into vapors. The pressure reducer system includes a liquid ejector having an inlet portion adapted to receive the liquid from the reservoir, a throat portion arranged downstream of the inlet portion and fluidly coupled to the evaporator and an outlet portion disposed downstream of the throat portion and configured to increase a pressure inside the liquid ejector. The pressure reducer system also includes a pump fluidly connected to the liquid ejector and the reservoir to supply the liquid from the reservoir to the liquid ejector.
