Analytical model for a vertical buoyant jet

Description: An analytical model for a round and two-dimensional turbulent buoyant jet which is discharged vertically into a stagnant ambient is developed. The buoyant jet is considered to have three separate zone models which are matched to form a complete solution. The velocity field is determined for the entire jet and plume regions by the use of an eddy viscosity which varies along the axis of the jet. The centerline decay of buoyancy is determined throughout and the results are compared to existing num… more

Performance estimates for personnel access control systems

Description: Current performance estimates for personnel access control systems use estimates of Type I and Type II verification errors. A system performance equation which addresses normal operation, the insider, and outside adversary attack is developed. Examination of this equation reveals the inadequacy of classical Type I and II error evaluations which require detailed knowledge of the adversary threat scenario for each specific installation. Consequently, new performance measures which are consistent … more

FEMWATER: a finite-element model of water flow through saturated-unsaturated porous media

Description: Upon examining the Water Movement Through Saturated-Unsaturated Porous Media: A Finite-Element Galerkin Model, it was felt that the model should be modified and expanded. The modification is made in calculating the flow field in a manner consistent with the finite element approach, in evaluating the moisture-content increasing rate within the region of interest, and in numerically computing the nonlinear terms. With these modifications, the flow field is continuous everywhere in the flow regime… more

Parity violation in polarized electron scattering

Description: The weak forces are responsible for the decay of radioactive nuclei, and it was in these decay processes where parity non-conservation was first observed. Beta decay occurs through emission of e/sup +/ or e/sup -/ particles, indicating that the weak force can carry charge of both signs, and it was natural to speculate on the existence of a neutral component of the weak force. Even though weak neutral forces had not been observed it was conjectured that a neutral component of weak decay could ex… more

Instruction manual for the program SHAPEFACTOR

Description: A numerical technique is presented for evaluating the geometrical radiant exchange factors (also called shape or view factors) between surfaces with interposed obstructions. Since the program is developed for plane surfaces, arbitrary surfaces are expressed by the juxtaposition of plane surfaces; to simplify the input and output, the program respectively combines and decomposes these elemental surfaces. The data input format, although designed for manual input, is ideally suited for standard th… more

Open-cycle OTEC system performance analysis. [Claude cycle]

Description: An algorithm developed to calculate the performance of Claude-Cycle ocean thermal energy conversion (OTEC) systems is described. The algorithm treats each component of the system separately and then interfaces them to form a complete system, allowing a component to be changed without changing the rest of the algorithm. Two components that are subject to change are the evaporator and condenser. For this study we developed mathematical models of a channel-flow evaporator and both a horizontal jet… more

Measurement techniques

Description: The discussion will be restricted to measurements of voltage and current. Also, although the measurements themselves should be as quantitative as possible, the discussion is rather nonquantitative. Emphasis is on types of instruments, how they may be used, and the inherent advantages and limitations of a given technique. A great deal of information can be obtained from good, clean voltage and current data. Power and impedance are obviously inherent if the proper time relationships are preserved… more

Organizing for nuclear power facility development. Final draft report

Description: Centralized power development concepts have been of interest for some years and have been given considerable study in the past, e.g., the Congressionally-directed 1975 NRC studies. In general, while all such studies have concluded that such Centers did offer potential benefits and were feasible, in the mid-1970's, when most of these studies were done, the advantages did not appear to make use of Energy Centers on balance, preferable to continued conventional or dispersed siting. The DOE recogni… more

Modules for estimating solid waste from fossil-fuel technologies

Description: Solid waste has become a subject of increasing concern to energy industries for several reasons. Increasingly stringent air and water pollution regulations result in a larger fraction of residuals in the form of solid wastes. Control technologies, particularly flue gas desulfurization, can multiply the amount of waste. With the renewed emphasis on coal utilization and the likelihood of oil shale development, increased amounts of solid waste will be produced. In the past, solid waste residuals u… more
