Synthetic liquid fuels development: assessment of critical factors. Volume IV. Energy/economic comparison of coal-based automotive energy supply systems

Considerable debate has occurred in recent years about the relative merits of energy analysis versus traditional economic analysis. Some economists assert that energy analysis adds no new information to that in economic analysis; energy analysts claim that the explicit consideration of energy flows is necessary for a complete understanding of the implications of energy supply and use. In comparing the cost and energy consumption figures for the various automotive energy options, certain paralle… more

Effects of binder concentration on the properties of plastic-bonded explosives

A series of plastic-bonded explosives (PBX) has been formulated with more binder than is normally contained in high-energy formulations. Adding a relatively small amount of binder to a material such as PBX 9501 (95/2.5/1.25/1.25 wt % HMX/Estane/BDNPA/BDNPF (the BDNPA and BDNPF form a eutectic that is frequently called simply the eutectic)) was found to decrease the shock sensitivity while not decreasing the energy of the explosive. The best compromise for a PBX 9501-type material contains about… more

Contributions of kinematics and viscoelastic lap deformation on the suface figure during full aperture polishing of fused silica

A typical optical fabrication process involves a series of basic process steps including: (1) shaping, (2) grinding, (3) polishing, and sometimes (4) sub-aperture tool finishing. With significant innovation and development over the years in both the front end (shaping using CNC machines) and the back end (sup-aperture tool polishing), these processes have become much more deterministic. However, the intermediate stages (full aperture grinding/polishing) in the process, which can be very time co… more

Weld procedure development with OSLW - optimization software for laser welding

Weld procedure development can require extensive experimentation, in-depth process knowledge, and is further complicated by the fact that there are often multiple sets of parameters that will meet the weld requirements. Choosing among these multiple weld procedures can be hastened with computer models that find parameters to meet selected weld dimensional requirements while simultaneously optimizing important figures of merit. Software is described that performs this task for CO{sub 2} laser be… more

Spot size and effective focal length measurements for a fast axial flow CO{sub 2} laser

An evaluation of the variation in focal plane position and spot size for a 1,650 W fast axial flow CO{sub 2} laser was performed. Multiple measurements of the focused beam were taken at stepped intervals along the beam axis to create a composite representation of the focus region. Measurements were made at several power levels from low to full power for each of five nominally identical lenses. It was found that as laser output power increases, the minimum focused spot radius increases, and the … more

An approach to the study of solid state bonding

The program objective has been to investigate the possible similarity between a bond interface and a grain boundary. The criterion for establishing the similarity of a bond interface and a grain boundary was the migration characteristics of the boundary under the influence of controlled orientation, strain level, temperature and time. In addition, the orientation dependency of the "threshold", or minimum deformation, for bonding would have to be determined. The initial bonding studies were to … more

The NO to NO{sub 2} conversion by ethylene oxidation

A well-stirred reactor experiment and chemical kinetic modeling effort were performed in order to study the effect of ethylene oxidation on the conversion of nitric oxide (NO) to nitrogen dioxide (NO{sub 2}). Parameters examined in this study were temperature (1003--1260K) and input hydrocarbon concentration (220--3270 ppmv wet). The stirred reactor residence time was maintained at {approximately}2 milliseconds. Kinetic calculations indicated the NO to NO{sub 2} conversion proceeded through the… more

Polishing slurry induced surface haze on phosphate laser glasses

The effects of residual polishing slurry on the surface topology of highly-polished, Nd-doped metaphosphate laser glasses are reported. Glass samples were pitched polished using cerium oxide or zirconium oxide slurry at different pHs and then washed by different methods that allowed varying amounts of residual slurry to ''dry'' on the surface. Upon re-washing with water, some of the samples showed surface haze (scatter), which scaled with the amount of residual slurry. Profilometry measurements… more

The effects of load-sensitive behavior on the operability margins of motor-operated gate valves

Testing of motor-operated gate valves at various loads has produced a phenomenon we call load-sensitive behavior. This phenomenon has a significant effect on the accuracy of the methods used (and proposed) in the nuclear industry for determining that these valves can perform their design basis function. A valve subjected to tests with low flow and pressure loadings may achieve a stem thrust (at seating) analytically determined to be adequate for design basis flows and pressures, but this is no … more

Fail-safe design for square vacuum-barrier windows

Laser-induced damage on the tensile side of vacuum-barrier fused silica optics can result in catastrophic fracture. This fracture can lead to two possible modes of failure: a benign failure resulting in a slow air leak into the vacuum chamber or an implosion. In previous work, they measured fracture in round vacuum windows and lenses and proposed a fail-safe design that would insure the benign failure mode by fracturing into only two parts, thus eliminating the possibility of implosion. In this… more
