Development of a One-Equation Transition/Turbulence Model (open access)

Development of a One-Equation Transition/Turbulence Model

This paper reports on the development of a unified one-equation model for the prediction of transitional and turbulent flows. An eddy viscosity - transport equation for non-turbulent fluctuation growth based on that proposed by Warren and Hassan (Journal of Aircraft, Vol. 35, No. 5) is combined with the Spalart-Allmaras one-equation model for turbulent fluctuation growth. Blending of the two equations is accomplished through a multidimensional intermittence function based on the work of Dhawan and Narasimha (Journal of Fluid Mechanics, Vol. 3, No. 4). The model predicts both the onset and extent of transition. Low-speed test cases include transitional flow over a flat plate, a single element airfoil, and a multi-element airfoil in landing configuration. High-speed test cases include transitional Mach 3.5 flow over a 5{degree} cone and Mach 6 flow over a flared-cone configuration. Results are compared with experimental data, and the spatial accuracy of selected predictions is analyzed.

Equation of State Measurements of Materials Using a Three-Stage Gun to Impact Velocities of 11km/s (open access)

Equation of State Measurements of Materials Using a Three-Stage Gun to Impact Velocities of 11km/s

Understanding high pressure behavior of homogeneous as well as heterogeneous materials is necessary in order to address the physical processes associated with hypervelocity impact events related to space science applications including orbital debris impact and impact lethality. At very high impact velocities, material properties will be subjugated to phase-changes, such as melting and vaporization. These phase states cannot be obtained through conventional gun technology. These processes need to be represented accurately in hydrodynamic codes to allow credible computational analysis of impact events resulting from hypervelocity impact. In this paper, techniques that are being developed and implemented to obtain the needed shock loading parameters (Hugoniot states) for material characterization studies, namely shock velocity and particle velocity, will be described at impact velocities up to 11 km/s. What is new in this report is that these techniques are being implemented for use at engagement velocities never before attained utilizing two-stage light-gas gun technology.

Estimating Worker Risk Levels Using Accident/Incident Data (open access)

Estimating Worker Risk Levels Using Accident/Incident Data

The purpose of the work described in this report was to identify methods that are currently being used in the Department of Energy (DOE) complex to identify and control hazards/risks in the workplace, evaluate them in terms of their effectiveness in reducing risk to the workers, and to develop a preliminary method that could be used to predict the relative risks to workers performing proposed tasks using some of the current methodology. This report describes some of the performance indicators (i.e., safety metrics) that are currently being used to track relative levels of workplace safety in the DOE complex, how these fit into an Integrated Safety Management (ISM) system, some strengths and weaknesses of using a statistically based set of indicators, and methods to evaluate them. Also discussed are methods used to reduce risk to the workers and some of the techniques that appear to be working in the process of establishing a condition of continuous improvement. The results of these methods will be used in future work involved with the determination of modifying factors for a more complex model. The preliminary method to predict the relative risk level to workers during an extended future time period is based on …

Neutronic feasibility studies for LEU conversion of the HFR Petten Reactor. (open access)

Neutronic feasibility studies for LEU conversion of the HFR Petten Reactor.

Design and safety analyses to determine an optimum LEU fuel assembly design using U{sub 3}Si{sub 2}-Al fuel with up to 4.8 g/cm{sup 3} for conversion of the HFR Petten reactor were performed by the RERTR program in cooperation with the Joint Research Centre and NRG. Credibility of the calculational methods and models were established by comparing calculations with recent measurements by NRG for a core configuration setup for this purpose. This model and methodology were then used to study various LEU fissile loading and burnable poison options that would satisfy specific design criteria.

Oral History Interview with Ross Taggart, September 26, 2000 transcript

Oral History Interview with Ross Taggart, September 26, 2000

The National Museum of the Pacific War presents an oral interview with Ross Taggart. Taggart was born 21 May 1921 in Twin Falls, Idaho. He joined the Navy in 1938. He was assigned to the USS Langley (CV-1) and was wounded when she was attacked by Japanese aircraft and sank in February, 1942. He was rescued by the USS Whipple (DD-217) and transferred to the USS Pecos (AO-6). Two days later, the Pecos was attacked and sank. He was wounded again in the attack and transferred back to the Whipple, which went to Australia. After a stay in the hospital in Australia, Taggart returned to duty and was assigned to the USS Bullwheel (YO-46). Taggart was transferred to shore duty on Iwo Jima where he was severely wounded and placed aboard the hospital ship USS Bountiful (AH-9) for return to the United States. He traveled by hospital train to the Great Lakes Naval Hospital and spent 18 months recovering. He received a medical discharge and went to school using the GI Bill where he received a degree in chemical engineering.

Perfluoro(Methylcyclohexane) Tracer Tagging Test and Demonstration (open access)

Perfluoro(Methylcyclohexane) Tracer Tagging Test and Demonstration

On February 14 and 15, 2000, a demonstration of current perfluorocarbon tagging technology and the future potential of these methods was held at Oak Ridge National Laboratory (ORNL). The demonstration consisted of a brief technical discussion followed by a laboratory demonstration. The laboratory demonstrations included the detection of letters, parcels, briefcases and lockers containing perfluorocarbon-tagged papers. Discrimination between tagged and non-tagged items and between three perfluorocarbon tags was demonstrated along with the detection of perfluorocarbon in a background of non-fluorinated volatile organic solvent. All demonstrations involved real-time detection using a direct sampling ion trap mass spectrometer. The technical results obtained at ORNL during and in preparation for the demonstration are presented in Appendix 1 to assist Tracer Detection Technology Corp. in further evaluating their position on development and marketing of perfluorocarbon tracer technology.
