Measurement of Airflow in Residential Furnaces (open access)

Measurement of Airflow in Residential Furnaces

In order to have a standard for furnaces that includes electricity consumption or for the efficiency of furnace blowers to be determined, it is necessary to determine the airflow of a furnace or furnace blower. This study focused on airflow testing, in order to determine if an existing test method for measuring blower airflow could be used to measure the airflow of a furnace, under conditions seen in actual installations and to collect data and insights into the operating characteristics of various types of furnace blowers, to use in the analysis of the electricity consumption of furnaces. Results of the measured airflow on furnaces with three types of blower and motor combinations are presented in the report. These included: (1) a forward-curved blower wheel with a typical permanent split capacitor (PSC) motor, (2) a forward-curved blower wheel with an electronically-commutated motor (ECM), and (3) a prototype blower, consisting of a backward-inclined blower wheel matched to an ECM motor prototype, which is being developed as an energy-saving alternative to conventional furnace blowers. The testing provided data on power consumption, static and total pressure, and blower speed.

An Appraisal of Coupled Climate Model Simulations (open access)

An Appraisal of Coupled Climate Model Simulations

In 2002, the Program for Climate Model Diagnosis and Intercomparison (PCMDI) proposed the concept for a state-of-the-science appraisal of climate models to be performed approximately every two years. Motivation for this idea arose from the perceived needs of the international modeling groups and the broader climate research community to document progress more frequently than provided by the Intergovernmental Panel on Climate Change (IPCC) Assessment Reports. A committee of external reviewers, which included senior researchers from four leading international modeling centers, supported the concept by stating in its review: ''The panel enthusiastically endorses the suggestion that PCMDI develop an independent appraisal of coupled model performance every 2-3 years. This would provide a useful 'mid-course' evaluation of modeling progress in the context of larger IPCC and national assessment activities, and should include both coupled and single-component model evaluations.''

Defense Infrastructure: Long-term Challenges in Managing the Military Construction Program

A letter report issued by the General Accounting Office with an abstract that begins "The Department of Defense's (DOD) military construction program provides funding for construction projects in the United States and overseas, and funds most base realignment and closure costs. Recent Office of the Secretary of Defense (OSD) estimates indicate that it would cost as much as $164 billion to improve facilities to a level that would meet the department's goals. GAO was asked to report on the (1) steps OSD has taken to enhance program management, (2) process of prioritizing and resourcing military construction projects, and (3) advantages and disadvantages of increasing the current funding thresholds for constructing and repairing facilities."

Deformation of Single Crystal Molybdenum at High Pressure (open access)

Deformation of Single Crystal Molybdenum at High Pressure

Single crystal samples of micron dimensions oriented in the [001] direction were shortened 10 to 40% in uniaxial compression with superposed hydrostatic pressure to begin investigation of how the onset of yielding evolves with pressure. A testing machine based on opposed anvil geometry with precision pneumatic control of the applied force and capability to measure sub micron displacements was developed to produce shape changing deformation at pressure. The experiments extend observations of pressure dependent deformation to {approx}5Gpa at shortening rates of {approx}2*10{sup -4}. Samples have been recovered for post run characterization and analysis to determine if deformation mechanisms are altered by pressure. Experiments under hydrostatic pressure provide insight into the nature of materials under extreme conditions, and also provide a means for altering deformation behavior in a controlled fashion. The approach has a long history demonstrating that pressure enhances ductility in general, and produces enhanced hardening relative to that expected from normal cold work in the BCC metals Mo, Ta and Nb{sup 2}. The pressure hardening is in excess of that predicted from the measured increase in shear modulus at pressure, and therefore is likely due to a dislocation mechanism, such as suppression of kink pair formation or the interaction …

Factors Affecting Zebra Mussel Kill by the Bacterium Pseudomonas fluorescens (open access)

Factors Affecting Zebra Mussel Kill by the Bacterium Pseudomonas fluorescens

The specific purpose of this research project was to identify factors that affect zebra mussel kill by the bacterium Pseudomonas fluorescens. Test results obtained during this three-year project identified the following key variables as affecting mussel kill: treatment concentration, treatment duration, mussel siphoning activity, dissolved oxygen concentration, water temperature, and naturally suspended particle load. Using this latter information, the project culminated in a series of pipe tests which achieved high mussel kill inside power plants under once-through conditions using service water in artificial pipes.

Improved Miscible Nitrogen Flood Performance Utilizing Advanced Reservoir Characterization and Horizontal Laterals in a Class I Reservoir - East Binger (Marchand) Unit Quarterly Report (open access)

Improved Miscible Nitrogen Flood Performance Utilizing Advanced Reservoir Characterization and Horizontal Laterals in a Class I Reservoir - East Binger (Marchand) Unit Quarterly Report

Implementation of the work program of Budget Period 2 of the East Binger Unit (''EBU'') DOE Project is progressing and nearing completion. Two of three planned horizontal wells have been drilled and completed. The third horizontal well will be replaced by two vertical wells, both of which will be drilled in early 2004. Based on costs and performances of all new wells, it is believed that, in the setting of the East Binger Unit, the benefits of horizontal wells do not justify the additional cost. In addition to the drilling of new wells, the project also includes conversions of producing wells to injection service. Four wells have now been converted, and injection in the pilot area has doubled. A fifth planned conversion has been removed from the project. Overall response to the various projects continues to be very favorable. Gas injection into the pilot area has increased from 4.0 MMscf/d prior to development to 8.0 MMscf/d in November, while gas production has decreased from 4.1 MMscf/d to 3.0 MMscf/d. The nitrogen content of produced gas has dropped from 58% to 45%. This has reduced the nitrogen recycle within the pilot area from 60% to under 20%. Meanwhile, pilot area oil …

LATTICE QCD AT FINITE TEMPERATURE AND DENSITY. (open access)

LATTICE QCD AT FINITE TEMPERATURE AND DENSITY.

With the operation of the RHIC heavy ion program, the theoretical understanding of QCD at finite temperature and density has become increasingly important. Though QCD at finite temperature has been extensively studied using lattice Monte-Carlo simulations over the past twenty years, most physical questions relevant for RHIC (and future) heavy ion experiments remain open. In lattice QCD at finite temperature and density there have been at least two major advances in recent years. First, for the first time calculations of real time quantities, like meson spectral functions have become available. Second, the lattice study of the QCD phase diagram and equation of state have been extended to finite baryon density by several groups. Both issues were extensively discussed in the course of the workshop. A real highlight was the study of the QCD phase diagram in (T, {mu})-plane by Z. Fodor and S. Katz and the determination of the critical end-point for the physical value of the pion mass. This was the first time such lattice calculations at, the physical pion mass have been performed. Results by Z Fodor and S. Katz were obtained using a multi-parameter re-weighting method. Other determinations of the critical end point were also presented, in …

LCLS prototype undulator report. (open access)

LCLS prototype undulator report.

The Linac Coherent Light Source (LCLS) undulator line will consist of 33 undulator segments separated by breaks of two different lengths. The undulator segments are 3.4-m-long permanent-magnet planar hybrid devices with a period length of 30 mm and a magnetic gap of approximately 6 mm. Focusing quadrupoles, in a FODO lattice, and electron-beam diagnostics will be located in the breaks between undulator segments. Every third break will be longer in order to also accommodate x-ray diagnostics. Thus, taking the alternating focusing and defocusing quadrupoles into account, the ''super-period'' length before the undulator line repeats itself is six undulator segments. For additional details on the LCLS project and the undulator line, please refer to the conceptual design report (CDR). A full-length prototype undulator segment has been designed, manufactured and tested, and this document provides a comprehensive report of our experience with the prototype. It contains sections on the overall design philosophy and presents many important measurements including magnetic measurements of the magnet blocks, as well as of the assembled device, and mechanical and thermal measurements. It also contains a summary section (section 5) and one section that summarizes some remaining issues being investigated (section 6).

NAFEMS Finite Element Benchmarks for MDG Code Verification (open access)

NAFEMS Finite Element Benchmarks for MDG Code Verification

NAFEMS was originally founded at the United Kingdom's National Engineering Laboratory as the National Agency for Finite Element Methods and Standards. It was subsequently privatized as the not-for-profit organization NAFEMS, Ltd., but retains its mission ''To promote the safe and reliable use of finite element and related technology''. That mission has been pursued in part by sponsoring a series of studies that published benchmarked deemed suitable to assess the basic accuracy of engineering simulation tools. The early studies focused on FEA for linear solid and structural mechanics and then extended to nonlinear solid mechanics, eventually including contact. These benchmarks are complemented by educational materials concerning analysis technologies and approaches. More recently NAFEMS is expanding to consider thermal-fluid problems. Further information is available at www.nafems.org. Essentially all major commercial firms selling FEA for solid mechanics are members of NAFEMS and it seemed clear that Methods Development Group should leverage from this information resource, too. In 2002, W Program ASCI funding purchased a three-year membership in NAFEMS. In the summer of 2003 the first author hosted a summer graduate student to begin modeling some of the benchmark problems. We concentrated on NIKE3D, as the benchmarks are most typically problems most naturally run …

PHOTOREDUCTIVE SEQUESTRATION OF CO2 TO FORM C1 PRODUCTS AND FUEL (open access)

PHOTOREDUCTIVE SEQUESTRATION OF CO2 TO FORM C1 PRODUCTS AND FUEL

We have investigated the photochemical reduction of CO{sub 2} in aqueous solution to form C{sub 1} products using a variety of oxide semiconductors and near UV light. Conventional oxide photosemiconductors including TiO{sub 2} and SrTiO{sub 3}, as well as modified oxide semiconductors including Pt/TiO{sub 2} and SrTiO{sub 3}/Cr-Sb, TiO{sub 2}/Fe{sub 3}O{sub 4} or TiO{sub 2}/Fe(CN){sub 6}{sup 3-} were used. Analysis for formate, acetate, formaldehyde, methanol and methane were conducted by a variety of analytical methods. Despite extensive published data on the facile reduction of CO{sub 2} by these semiconductors, we found only trace quantities of formate and acetate (typically less than 1 ppm) and no unequivocal evidence for formation of the other products. The quantum efficiencies of TiO{sub 2} and SrTiO{sub 3} for forming formate and acetate from CO{sub 2} are estimated to be 0.1-0.2% or less. The spectral properties of the unmodified oxides (TiO{sub 2}, SrTiO{sub 3}) restricts their use of solar irradiation to about 10% of the available near UV and visible spectrum, thereby giving an overall quantum and spectral efficiency of less than 0.01%. Semiconductor oxides modified with, Cr and Sb, Fe{sub 3}O{sub 4} or Fe(CN){sub 6}{sup 3-} exhibited no enhanced efficiency. However, Pt/TiO{sub 2} does produce …
