Investigation of heat exchanger flow arrangement on performance and cost in a geothermal binary cycle

Description: The performance of an idealized geothermal binary-fluid-cycle energy conversion system is shown to be a function of the temperatures of brine and working fluid leaving the heat exchanger. System power output, heat exchanger area required and initial well and heat exchanger costs are determined for counterflow, single and multi-pass parallel-counterflow exchangers. Results are presented graphically as functions of the brine and working fluid exit temperatures from the exchanger. Use of the syste… more

Large area silicon sheet by EFG. Third quarterly progress report, April 1, 1976--June 30, 1976

Description: The ''wide'' ribbon machine, JPL No. 1, is satisfactorily nearing completion. Heat sinks to accelerate growth rates were tested. Although horizontal gradients can be tailored with the heat sinks, no growth rate improvement was realized. The electrical effects of linear boundaries have been studied. Thin ribbon growth as an immediate task is reconsidered.

Heat transfer and pressure drop characteristics of dry tower extended surfaces. Part II. Data analysis and correlation

Description: A summary is presented of studies of the heat transfer and pressure drop characteristics of extended surfaces. The summary is based on data that were compiled and analyzed with the objectives of determining the effects of geometrical configurations of an extended surface tube bank on its heat transfer and pressure drop characteristics. A generalized correlation of heat transfer and friction losses was developed on the basis of this analysis. These correlations can be used to predict the perform… more

Silicon Ribbon Growth by a Capillary Action Shaping Technique

Description: The crystal-growth method under investigation is a capillary action shaping technique. Meniscus shaping for the desired ribbon geometry occurs at the vertex of a wettable die. As ribbon growth depletes the melt meniscus, capillary .action. supplies replacement material. In this report, a new capillary die design is described. It represents a departure from the die types used for edge-defined, film-fed growth, in that the bounding edges of the die top are not parallel or concentric with the grow… more

BIPS-FS preliminary design, miscellaneous notes

Description: A compendium of flight system preliminary design internal memos and progress report extracts for the Brayton Isotope Power System Preliminary Design Review to be held July 20, 21, and 22, 1975 is presented. The purpose is to bring together those published items which relate only to the preliminary design of the Flight System, Task 2 of Phase I. This preliminary design effort was required to ensure that the Ground Demonstration System will represent the Flight System as closely as possible.

Fatigue tests of dowel-socket systems. [HTGR]

Description: A test program was conducted to determine the fatigue behavior of LHTGR fuel element dowel/socket systems. Two dowel/socket systems, namely, a four-dowel system and a five-dowel system, were tested to failure under shear loads applied through a fatigue test apparatus to simulate repetitive loading during a seismic event.

Review of applicable technology: solution mining of caverns in salt domes to serve as repositories for radioactive wastes

Description: There is an abundance of salt domes in the Gulf Coastal region. Advances in leaching technology and cavern shape control make it possible to build large caverns with configurations approaching teardrops, cylinders, and spheres. Fenix and Scisson has designed and constructed several dozen caverns in sizes up to three million barrels (16.8 million cubic feet). It is now within current technological bounds to evacuate the brine left in the cavern following construction, dehumidify the cavern atmos… more
