  • The experimental characterization of membrane behavior in two-phase gas extraction

    Creator:
    Cappello, Nicholas C.
    Abstract:
    Understanding the behavior of hydrophobic membranes is important for applications where separating a gas from a liquid-gas mixture is beneficial. For example, in-situ vapor extraction can be used in microscale heat sinks to improve heat transfer and flow stability. In this study, gas is experimentally evaluated flowing through flexible polytetrafluoroethylene...

  • Modeling convective boiling flow with in-situ local vapor extraction

    Creator:
    Salakij, Saran
    Abstract:
    The pressure drop of convective boiling flow may be reduced by extracting vapor locally since the entire generated vapor does not have to travel through the entire channel length. In this study, the theoretical model was developed to simulate a convective boiling flow through a fractal-like branching microchannel network with...

  • Modeling in-situ vapor extraction during flow boiling in microscale channel

    Creator:
    Salakij, Saran
    Abstract:
    In-situ vapor extraction is performed by applying a pressure differential across a hydrophobic porous membrane that forms a wall of the channel as a means of reducing the local quality of flow boiling within the channel. As the local quality is reduced, the heat transfer capability can be improve while...
