New submissions to the thesis/dissertation collections are added automatically as they are received from the Graduate School. Currently, the Graduate School deposits all theses and dissertations from a given semester after the official graduation date. This means that there may be up to a 4 month delay in the appearance of a give thesis/dissertation in DRUM

    Spray Characteristics From Fire Hose Nozzles
    (2010) Salyers, Brian Edward; Marshall, Andrew W; Fire Protection Engineering; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)
    This research examines the spray characteristics of fire hose streams. Smooth bore fire hose nozzles create jets with shear column breakup due to high Weber numbers. Laboratory settings produced a cylindrical water jet with the same column breakup behavior. The jet was injected into still air with fully developed turbulent flow. The test nozzle was oriented parallel to the floor. A patternator defined the shape and distribution of the spray. Shadowgraphy measurements determined the flow, drop size and velocity. The spray was tested in the middle of the liquid core.
