Flow through three-dimensional arrangements of cylinders with alternating streamwise planar tilt. Final report, ending September 1993

Description: In this report, fluid flow through a three-dimensional model for the fibrous filters is examined. In this model, the three-dimensional Stokes equation with the appropriate periodic boundary conditions is solved using the finite volume method. In addition to the numerical solution, we attempt to model this flow analytically by using the two-dimensional extended analytic solution in each of the unit cells of the three-dimensional structure. Particle trajectories computed using the superimposed an… more

Fundamental studies of coal liquefaction. Quarterly report No. 8, July 1, 1993--October 1, 1993

Description: In the last report the effects of water, tetralin, and argon were discussed as media during the heating of Illinois No. 6 coal. In studies in which the temperature was ramped from ambient to 460{degrees}C at 30{degrees}C/min particles were observed to shrink in the case of both water and tetralin, and first swell and then collapse back to particles with their starting shapes in the case of argon. The result with tetralin was expected, but that for water was not. Similarly, the results in argon … more

Technology development for cobalt F-T catalysts. Quarterly technical progress report No. 4, July 1, 1993--September 30, 1993

Description: The goal of this project is the development of a commercially viable, cobalt-based Fischer-Tropsch (F-T) catalyst for use in a slurry bubble column reactor. Cobalt-based catalysts have long been known as being active for F-T synthesis. They typically possess greater activity than iron-based catalysts, historically the predominant catalyst being used commercially for the conversion of syngas based on coal, but possess two disadvantages that somewhat lessen its value: (1) cobalt tends to make mor… more

Estimation of Ni{sup 63}, Pu{sup 241}, Pu{sup 242} and Am{sup 243} from Co{sup 60}, Pu{sup 239}, and Cm{sup 244} activities in groundwater samples

Description: The Part B Permit for F&H Seepage Basins calls for analysis of several constituents of concern in groundwater monitoring wells. Four of these analytes are the radionuclides Ni{sup 63}, Pu{sup 241}, Pu{sup 242}, and Am{sup 243}. These are currently not being analyzed due to their very difficult, tedious analytical schemes coupled with their relatively low activity values. This report demonstrates how the activity value for Ni{sup 63}, a week beta emitter, can be estimated from that of Co{sup 60}… more

Advanced fusion diagnostics. Final technical report, July 15, 1991--July 14, 1993

Description: Key among various issues of ignited plasmas is understanding the physics of energy transfer between thermal plasma particles and magnetically confined, highly energetic charged ions in a tokamak device. The superthermal particles are products of fusion reactions. The efficiency of energy transfer by collisions, from charged fusion products (e.g., {alpha}-particles) to plasma ions, grossly determines whether or not plasma conditions are self-sustaining without recourse to auxiliary heating. Furt… more

Fundamental studies of coal liquefaction. Quarterly report No. 7, April 1--July 1, 1993

Description: In our last report we discussed observations in our cell concerning the behavior or Illinois No. 6 coal in tetralin to 460{degrees}C. We noted that there were possibly two distinct types of particles comprising the organic phase, reacting respectively at 420{degrees}--430{degrees}C, and at 450{degrees}--460{degrees}C. Alternatively we could interpret the data as describing a range of reactivity bounded by those temperatures. As evidenced by the contraction of the particles, the reactions were r… more

Japanese Officials' View of Relations with the Clinton Administration, May-June 1993

Description: Japanese officials interviewed for this project in May-early June 1993 were generally sanguine about relations with the United States at the start of the Clinton Administration, but the Administrations's strong emphasis on U.S.- Japan trade issues in recent months deepened their pessimism over the near term prospects of U.S.-Japan relations. They were uncertain whether U.S.- Japanese talks on trade issues prior to the Clinton-Miyazawa summit of July 1993 would reflect a basic change in U.S. tra… more
