  • Self-propelled motion of film boiling droplets on ratchet-like surfaces 

    Melling, Laura (University of Oregon, 2003-06)
    We have observed a novel phenomenon by which asymmetrically structured surfaces can be used to direct the motion of film boiling droplets without applying an external force to the system. Droplets placed on such a surface ...
  • Leidenfrost Ratchets 

    Taormina, Michael James (2006-07-07)
    A “Leidenfrost ratchet” is a device which facilitates a newly-discovered phenomenon, where drops of liquid accelerate across a heated substrate. The system has been qualitatively studied and a vapor flow model has been ...
