Three-dimensional temperature history of a multipass filled weldment. Part 2. [HEATINGS]

Description: Computer simulation of the three-dimensional temperature history in a multipass filled weldment was attempted by modifying a transient heat transfer code, HEATING5. The model includes temperature-dependent physical parameters, radiation and convection heat losses, turbulent and laminar convection in the molten pool, and variable arc velocity, intensity, and weld geometry. The model requires approximately 28 CPU min to simulate one second of welding. 15 figures, 8 tables.

Fission product data for thermal reactors. Part 2. Users manual for EPRI-CINDER code and data

Description: The objective of this project has been the production of a data library suitable for calculating the buildup of fission product nuclides during the operation of a thermal power reactor. This has been accomplished by reducing the fission product data from the fourth version of the national reference nuclear data base--ENDF/B into a series of linearized decay chains and calculating the effective yields and cross sections of the relevant nuclides. Two versions of the fission product library have b… more

900-755 degradation model for an RTG with a silicon-germanium thermopile. [DEGRA computer code]

Description: This report describes the RTG degradation mechanisms which have been identified as occurring in thermoelectric power generating systems that use the alloy of silicon germanium as the thermoelectric material and that incorporate a multifoil thermal insulation system. The synergetic effects of all of the identified degradation mechanisms are determined by a computer code, DEGRA, which calculates the available generator output power as a function of generator operating time.

Two-phase flow in geothermal energy sources. Progress report No. 1: eight month period, October 1, 1975-May 30, 1976

Description: A detailed parametric study of the major variables that affect the pressure profile in the geothermal well, and hence its performance, was conducted in order to identify and define the pertinent problems that require further experimental and theoretical investigation. The well and, in particular, its two-phase section were modeled on the basis of sound two-phase flow principles. A computer algorithm was developed for pressure profile calculations and simulation of well performance. The algorith… more

Thermodynamic model of the hydrolysis of microcline in acid-sulfate solutions

Description: A theoretical model of the hydrolysis of microcline by a hydrothermal solution has been determined for a closed system at constant temperature. Hypothetical solution compositions and temperatures were chosen to match the known geothermal system at Roosevelt Hot Springs, Utah. The calculated reaction paths indicate that the overall reaction process is an exchange of potassium from the reactant mineral, microcline, for hydrogen from the solution. Aluminum is nearly conserved among solid phases. T… more

GRAY: a program to calculate gray-body radiation heat-transfer view factors from black-body view factors

Description: Program GRAY is written to perform the matrix manipulations necessary to convert black-body radiation heat-transfer view factors to gray-body view factors as required by thermal analyzer codes. The black-body view factors contain only geometric relationships. Program GRAY allows the effects of multiple gray-body reflections to be included. The resulting effective gray-body factors can then be used with the corresponding fourth-power temperature differences to obtain the net radiative heat flux.… more

Mathematical model for the preliminary analysis of dual-mode space nuclear fission solid core power and propulsion systems, NUROC3A. AMS report No. 1239a

Description: The three-volume report describes a dual-mode nuclear space power and propulsion system concept that employs an advanced solid-core nuclear fission reactor coupled via heat pipes to one of several electric power conversion systems. Such a concept could be particularly useful for missions which require both relatively high acceleration (e.g., for planetocentric maneuvers) and high performance at low acceleration (e.g., on heliocentric trajectories or for trajectory shaping). The first volume dev… 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

Using Mortran to translate Fortran programs from one machine to another. [IBM. -->. CDC]

Description: The Mortran processor was slightly modified, and a new set of macros was written, to act as an aid in the translation of IBM Fortran programs to CDC Fortran. A 30,000-source-card program was successfully converted by using the resulting package. The capabilities and limitations of this approach to Fortran conversion are described, and two examples of the output of the package are given.
