Thermal depletion of a geothermal reservoir with both fracture and pore permeability

Description: A method for estimating the useful lifetime of a reservoir in porous rock where the injection and production wells intersect a fracture system is presented. Equations were derived for the pore-fluid and fracture-fluid temperatures averaged over large regions of the geothermal field. Problems such as incomplete areal sweep and interfingering of cool and hot fluids are ignored. Approximate equations relating average temperatures to the heat flowing from rock to fluid were developed, and their use… more

Geothermal direct-contact heat exchange. Final report

Description: A glass direct contact heat exchange column was operated in the laboratory at atmospheric pressure using hot water and normal hexane. Column internals tested included an empty column, sieve trays, disk-and-doughnut trays, and two types of packing. Operation was very smooth in all cases and the minimum temperature approaches varied from less than 1{sup 0}C for packing to 13{sup 0}C for the empty column. High heat transfer rates were obtained in all cases, however, columns should be sized on the … more

Response of rocks to large stresses. [Model for predicting response of ductile and brittle rocks to impact loading]

Description: To predict the dimensions and characteristics of impact- and explosion-induced craters, one must know the equation of state of the rocks in which the crater is formed. Recent experimental data shed light upon inelastic processes that influence the stress/strain behavior of rocks. We examine these data with a view to developing models that could be used in predicting cratering phenomena. New data is presented on the volume behavior of two dissimilar rocks subjected to tensile stresses.

Annual progress report. [Nonlinear saturation of instabilities; linear stability theory for tokamaks]

Description: Research has been carried out in two broad areas, nonlinear saturation of instabilities in collisionless plasma and incorporation of important physical phenomena into linear stability theories appropriate to Tokamaks. The nonlinear work has established a general technique for dealing with the singular functions which arise and is now applied to the collisionless drift, the dissipative trapped electron in linear geometry and the drift cyclotron loss cone. Multimode problems are under study. The … more

Lithium--water--air battery project: progress during the month of October 1976. [Characterization of Li/I/sub 2/ and Li/Br/sub 2/ batteries]

Description: Experimental work in the area of the ambient-temperature, steady-state behavior of the lithium electrode was completed. The following conclusions were drawn: 100 percent coulombic efficiency may be approached over a wide range of concentrations, flow conditions, and current densities; coulombic efficiency is approximately equal to I/sub e//I/sub l/, and I/sub e/ is the current in the external circuit, and I/sub l/ is the diffusion-limited current. Li electrode resistivities of (0.4 to 1.0) x 10… more

Estimation of aerosol plutonium transport by the dust-flux method: a perspective on application of detailed data

Description: Two methods of dust-flux measurements are discussed which have been utilized to estimate aerosol plutonium deposition and resuspension. In previous studies the methods were found to be sufficiently detailed to permit parameterization of dust-flux to the erodibility of the soil, and a seventh-power dependency of dust-flux (or plutonium flux) to wind speed was observed in worst case conditions. The eddy-correlation method is technically more difficult, requires high-speed data acquisition, and re… more

Effects of the trip phenomenon on the toughness of heat treatable alloy steels. [AISI 4330]

Description: It is shown that substantial amounts of untransformed austenite may be obtained in low alloy steels by a combination of alloy modification (addition of silicon) and heat treatment. In silicon modified AISI 4330 steel, the amount of untransformed austenite is varied by utilizing isothermal treatments both above and below the M/sub s/. The stability of the untransformed austenite is found to be dependent on the amount of silicon and also on the tempering temperature. A magnetic saturation techniq… more

Preliminary users manual for BBC. [In LLL FORTRAN (LRLTRAN) for CDC-7600 computer]

Description: BBC is a two-dimensional, multifluid Eulerian hydro code based on the code KRAKEN and some later development. Either cylindrical or slab problems can be run. The grid is bounded by a rectangular band of empty boundary zones. The interfaces between the regular and boundary zones can be selected to be either rigid or vacuum interfaces. The setup for BBC problems is described in the KEG manual. The present report includes several options not available in the original version of BBC. (RWR)

Description: Tritiated Liquid Waste Decontamination (Molecular Excitation): A preliminary economic study of water detritiation by laser isotope separation indicates possible advantages over the catalytic exchange process. The electric power requirements are a factor of 5 lower, resulting in a 50-percent reduction in operating costs. Capital costs for the two methods appear comparable. Additional attempts were made to determine the ir spectrum of HTO around the ..nu../sub 1/ band. However, carbon dioxide imp… more

Numeric processor and text manipulator for the ''MASTER CONTROL'' data-base-management system

Description: The numeric and text processor of the MASTER CONTROL (MCP) data-base-management system permits the user to define fields and arrays that are functionally dependent on the data retained in a data base. This allows the storage of only the essential and unique information and data, and the calculation of derivable quantities as required. The derived quantity can be expressed as an arithmetic expression, that is, a functional relationship. Functions can be multiply subscripted and can be embedded w… more

Feasibility of a MHD generator as a transmitter for electromagnetic sounding of the earth. [Mathematical models]

Description: Development of a high-intensity source for use in time-domain electromagnetic (TDEM) soundings would permit investigation of geothermal systems to much greater depth than is now possible with controlled-source methods. The development of such a source is critically dependent upon a powerful, mobile generator. Magnetohydrodynamic pulse generators satisfy the weight and power requirements for such a generator. However, existing MHD generators which are used in geophysical applications are solid f… more
