  • Constrained thin film desorption through membrane separation

    Creator:
    Thorud, Johnathan D.
    Abstract:
    A constrained thin film desorption scheme has been experimentally tested to determine the desorption rates for water from an aqueous lithium bromide mixture through a confining membrane. Variable conditions include the inlet concentration, pressure differential across the membrane, and channel height. Desorption takes place in a channel created between two...

  • An experimental study of ammonia-water bubble absorption in a constrained microscale film

    Creator:
    Jenks, Jeromy W.
    Abstract:
    An experimental study of absorption of ammonia into a constrained thin film of ammonia-water solution is presented. A large aspect ratio microchannel with one of its walls formed by a porous material is used to constrain the thickness of the liquid film. Experiments were performed at a pressure of 1,...
