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

    Outflow boundary conditions for low-Mach buoyant computational fluid dynamics
    (2013) Trettel, Benjamin Michael; Trouve, Arnaud C; Fire Protection Engineering; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)
    General issues with outflow boundary conditions are discussed, as are the issues specific to flow with buoyancy such as unphysical build-up of fluid at the outflow boundary. Different solutions to these problems are detailed. The sponge-layer approach is used to model the outflow boundary in buoyant jets. The successes and shortcomings of the sponge-layer approach are made clear through comparisons with long domain simulations.
