The U.S. DOE Office of Environmental Management (EM) was created in 1989 to manage the cleanup of large areas of environmentally contaminated sites. Since the closure of many of these sites, U.S. taxpayers have spent about $220 billion at 74 cleanup sites. However, these sites were the smallest and most manageable sites to clean. There are still over 40 sites that are deemed as eno ...

Many contaminated DOE sites are located in arid regions where depth to groundwater is significant and/or contaminants were discharged into a vadose zone through which transport to the groundwater table is dominated by unsteady, unsaturated groundwater flow. The absence of an effective means to monitor vadose zone moisture content in profile has been a persistent impediment to developing and calibr ...

Increased use of Exhaust Gas Recirculation (EGR) combined with engine downsizing has pushed automotive turbocharger compressor operation towards and often beyond its efficient and stable operating boundaries. Much of the drive cycle is spent operating the compressor at low flow rates and low pressure ratios, near the compressor surge line, in an area which is usually of low efficiency. Our prelimi ...

Nuclear power is a key component in the strategy to meet the countrys energy goals and technologies are needed to improve the reliability of current reactors and disposing safely of nuclear wastes. Vitrification is considered the preferred process for nuclear waste disposal and the U.S. Department of Energy (DOE) currently approves only borosilicate glasses (BS) for that purpose. However, many nuc ...

ABSTRACT: High Energy X-ray computed tomography (CT) is used to inspect the integrity of solid rocket motors. The purpose of this proposal is to improve the detection of defects when they are obscured due to physical limitations of CT. Lickenbrock has developed an advanced variant of the expectation-maximization (EM) algorithm, and other algorithms, for improving fidelity of CT. The EM algorit ...

ABSTRACT: Flow Modeling and Simulation, LLC (FMS), proposes to develop a computational software tool, herein designated AUG3D, that is intended to provide physics-based, multi-level, validated computational simulations of turbine engine component flow fields, particularly those associated with thrust augmentors, i.e., afterburners. This tool will be ideally suited for closely integrating physica ...

ABSTRACT: Under this Small Business Technology Transfer (STTR) program, Innovative Technology Applications Company (ITAC), LLC and the University of Notre Dame (UND) are working to develop new optical instruments that will enable nonintrusive, off-body measurements of flow parameters in hypersonic flight. The two concepts under development by the ITAC/UND team and described in this proposal invo ...

ABSTRACT: The SCRAMSIM computer code will be able to perform analysis for engineering design, stemming from a low order Reynolds Average Navier-Stokes (RANS) to high order (4th or higher) LES using accurate subgrid scale models (SGS). It will also solve thermal non-equilibrium mechanisms, conjugated heat transfer, general finite-rate chemistry using several databases for hydrocarbon/hydrogen-air ...

This proposal offers the demonstration of an approach to integrate the latest corrosion sensor technology with corrosion structural effects modeling to enable the transition from periodic corrosion inspections to an efficient, focused prognostics and health monitoring (PHM) system. The fundamental vision of the proposed program is to provide the customer with a demonstrated process suitable for in ...

Appareo Systems, LLC, proposes to develop a functional prototype head-mounted position and orientation system (HPOS). The HPOS will be capable of operating in electromagnetic fields of up to 200 volts/meter and will provide at least one degree of accuracy and at least one degree of resolution at a 60 Hz update rate while providing 3 degree of freedom (DOF) information on head orientation, includi ...
