3-D Finite Element Analysis of Induction Logging in a Dipping Formation

Description: Electromagnetic induction by a magnetic dipole located above a dipping interface is of relevance to the petroleum well-logging industry. The problem is fully three-dimensional (3-D) when formulated as above, but reduces to an analytically tractable one-dimensional (1-D) problem when cast as a small tilted coil above a horizontal interface. The two problems are related by a simple coordinate rotation. An examination of the induced eddy currents and the electric charge accumulation at the interfa… more

13th TOPICAL CONFERENCE ON HIGH TEMPERATURE PLASMA DIAGNOSTICS SCIENTIFIC PROGRAM

Description: Electron cyclotron emission (ECE) has been employed as a standard electron temperature profile diagnostic on many tokamaks and stellarators, but most magnetically confined plasma devices cannot take advantage of standard ECE diagnostics to measure temperature. They are either overdense, operating at high density relative to the magnetic field (e.g. {omega}{sub pe} >> {Omega}{sub ce} in a spherical torus) or they have insufficient density and temperature to reach the blackbody condition ({… more

A 1D Analysis of Direct and Indirect Drive Target Performance for Planar Hydrodynamics Experiments on the NIF

Description: The 1D performance of laser or X-ray driven targets to study phenomena such as the Richtmyer-Meshkov instability in a single, steady shock, step down in density system has been described by a simple model based on 1D hydrodynamics. It is shown that the distance the interface travels under constant velocity conditions is a multiple of the separation between the ablation and shock front, and that this multiple depends on the density ratio at the interface, and the equations of states of the two m… more

2D numerical simulation of the resistive reconnection layer

Description: In this paper the authors present a two-dimensional numerical simulation of a reconnection current layer in incompressible resistive magnetohydrodynamics with uniform resistivity in the limit of very large Lundquist numbers. They use realistic boundary conditions derived consistently from the outside magnetic field, and they also take into account the effect of the backpressure from flow into the separatrix region. They find that within a few Alfven times the system reaches a steady state consi… more

Ab-Initio Step- and Kink-Formation Energies on Pb(111)

Description: Ab-initio formation energies for (100)- and (111)-microfacet steps on Pb(111) are in satisfactory agreement with measured values, given that these values are known only as well as the Pb(111) surface energy; the calculated step-energy ratio, 1.29, is within {approximately}8% of experiment. In contrast, calculated kink-formation energies, 41 and 60 meV for the two step types, are 40--50% below published experimental values derived from STM images. The discrepancy results from interpreting the im… more

Access Grid: Immersive Group-to-Group Collaborative Visualization

Description: Immersive projection displays have played an important role in enabling large-format virtual reality systems such as the CAVE and CAVE like devices and the various immersive desks and desktop-like displays. However, these devices have played a minor role so far in advancing the sense of immersion for conferencing systems. The Access Grid project led by Argonne is exploring the use of large-scale projection based systems as the basis for building room oriented collaboration and semi-immersive vi… more

Advanced Cuttings Transport Study Annual Report: 2000

Description: ACTS flow loop is now operational under elevated pressure and temperature. Currently, experiments with synthetic based drilling fluids under pressure and temperature are being conducted. Based on the analysis of Fann 70 data, empirical correlations defining the shear stress as a function of temperature, pressure and the shear rate have been developed for Petrobras synthetic drilling fluids. PVT equipment has been modified for testing Synthetic oil base drilling fluids. PVT tests with Petrobras … more

The AERI/GOES Retrievals Versus Radiosondes for Driving SCMs

Description: Single-Column Models (SCMs) require observations to provide suitable initial and boundary conditions. To meet this need, the Atmospheric Radiation Measurement (ARM) program conducts Intensive Observing Periods (IOPs) to provide 3-hourly radiosondes and other observations. However, such high-frequency sonde launches can be expensive. Therefore, the ARM program can only support a couple IOPs each year with each one lasting 2-4 weeks. In order to reduce the need for high-frequency sonde launches a… more

Analysis of Laser Tracker and Total Station Surveys

Description: The SMX 4500 laser tracker has proven itself to be a beneficial addition to SLAC's set of alignment tools. Through actual field surveys and laboratory testing, a question regarding some unknown scale factor appearing after adjusting the combined tracker and total station results arose. Through a simple line survey and instrument analysis and then progressing through more and more rigorous network adjustments, the authors deduced that the apparent scale problem was in fact more likely attributed… more

An analysis of tank and pump pit flammable gas data in support of saltwater pumping safety basis simplification

Description: Hanford Site high-level waste tanks are interim stabilized by pumping supernatant and interstitial waste liquids to double-shell tanks (DSTs) through a saltwell pump (SWP). The motor to this SWP is located atop the tank, inside a pump pit. A pumping line extends down from the pump motor into the well area, located in the salt/sludge solids in the tank below. Pumping of these wastes is complicated by the fact that some of the wastes generate and retain potentially hazardous amounts of hydrogen, … more

Analysis of the November 1999 Dead Sea Calibration Shots

Description: In November 1999 three chemical explosions were conducted in the Dead Sea for the purposes of calibrating the International Monitoring System (IMS) for the Comprehensive Nuclear-Test-Ban Treaty (CTBT). These shots were organized and conducted by the Geophysical Institute of Israel (GII). Large chemical explosions are the most valuable form of ground truth as the location, depth and origin time are very well known. We focus on the two largest shots (M{sub w} {ge} 3.6) and performed several types… more
