Energy programs at the Johns Hopkins University Applied Physics Laboratory. Quarterly report, October--December 1978 (open access)

Energy programs at the Johns Hopkins University Applied Physics Laboratory. Quarterly report, October--December 1978

The Johns Hopkins University Applied Physics Laboratory, under contracts with the U.S. Department of Energy, the National Science Foundation, U.S. Maritime Administration, Maryland Department of Natural Resources, U.S. Department of Commerce, and U.S. Fish and Wildlife Service, is engaged in developing energy resources, utilization concepts, and storage methods. This report is divided into four sections. The first, Geothermal Energy Programs, contains reports on various geothermal investigations in the Atlantic Coastal Plain; a Geothermal Energy Market Survey and a development scenario for the Delmarva area of Maryland. The second, Small-Scale Hydroelectric Energy, contains the results of several major studies on dams and on the economic and institutional issues related to their redevelopment. The third section contains progress reports on two major tasks performed for the Ocean Thermal Energy Conversion (OTEC) Program, Ocean Engineering and Heat Exchangers for OTEC systems. The fourth section, Conservation and Mechanical Storage of Energy, contains reports on flywheels and a JHU-funded heat pump application to the physical plant at APL.

Energy programs. Quarterly report, January-March 1978 (open access)

Energy programs. Quarterly report, January-March 1978

The Johns Hopkins University Applied Physics Laboratory is engaged in the development of energy resources, energy utilization concepts, and energy storage methods. This Quarterly Report, summarizing work completed on the various tasks as of 31 March 1978, contains comments on limited tasks, short descriptions of meetings, trips, presentations, and other limited tasks of note performed in connection with major program tasks and articles that describe these program tasks briefly, summarize the progress made to date, and indicate future efforts to be made. The major tasks fall into the following categories: Geothermal Energy Development Planning, which concentrates on the survey of potential geothermal resources and the development of scenarios for possible exploitation and utilization in DOE/DGE Region 5, which includes all the United States east of the Rocky Mountains, excluding Texas and Louisiana; Applications Study of DOE/DGE Region 5, which concerns a study of geothermal energy applications in DOE-selected areas of the Atlantic Coastal Plain; the Low-Head Hydroelectric Program; the Community Annual Storage Energy System (CASES) and the status of a development and demonstration plan for a low-cost flywheel; and multiple-objective modeling of power plant locations.

Energy programs. Quarterly report, January-March 1980

The Johns Hopkins University Applied Physics Laboratory, is engaged in developing energy resource, utilization concepts, and monitoring and storage methods. This Quarterly Report summarizes the work on the various tasks as of 31 March 1980. The Energy Quarterly Report is divided into four sections. The first, Geothermal Energy Development Planning and Technical Assistance, contains reports on the progress of geothermal-related tasks on which effort was concentrated during the quarter. The second section, Operational Research, Hydroelectric Power Development, contains reports on small-scale hydroelectric investigations in the southeastern states. The third section, Seismotectonic Investigation, reports on a neotectonic investigation in Connecticut. The fourth section, Energy Conversion and Storage Techniques, contains two articles, the first on OTEC core unit testing supported by the Department of Energy/Division of Central Solar Technology (DOE/CST), and the second on an analysis of the Community Annual Storage Energy System at the US Naval Air Station, Norfolk, Va.

Solar wind iron abundance variations at solar wind speeds > 600 km s/sup -1/, 1972 to 1976 (open access)

Solar wind iron abundance variations at solar wind speeds > 600 km s/sup -1/, 1972 to 1976

We have analyzed the Fe/H ratios in the peaks of high speed streams (HSS) during the decline of Solar Cycle 20 and the following minimum (October 1972 to December 1976). We utilized the response of the 50 to 200 keV ion channel of the APL/JHU energetic particle experiment (EPE) onIMP-7 and 8 to solar wind iron ions at high solar wind speeds (V greater than or equal to 600 km sec/sup -1/), and compared our Fe measurements with solar wind H and He parameters from the Los Alamos National Laboratory (LANL) instruments on the same spacecraft. In general, the Fe distribution parameters (bulk velocity, flow direction, temperature) are found to be similar to the LANL He parameters. Although the average Fe/H ration in many steady HSS peaks agrees within observational uncertainties with the nominal coronal ratio of 4.7 x 10/sup -5/, abundance variations of a factor of up to 6 are obtained across a given coronal-hole associated HSS. There are, as well, factor of 2 variations between stream-averaged abundances for recurent HSS emanating from different coronal holes occurring on the sun on the same solar rotation. flare-related solar wind streams sometimes show Fe/H ratios enhanced by factors of 4 to …

The Unstable Species and the Isotope Effect in the Pyrolysis of Diborane in a Shock Tube (open access)

The Unstable Species and the Isotope Effect in the Pyrolysis of Diborane in a Shock Tube

From American Chemical Society 145th National Meeting, New York, Sept. 1963. The pyrolysis of diborane was examined using a chemical shock tube as a reactor. Additional evidence for the existence of hexaborane-12 and heptaborane- 11 and -13 was obtained. The presence of a large net normal isotope effect in the formation of tetraborane and hexaborane and a net inverse isotope effect in the formation of pentaborane-9 are observed. A mechanism, consisting of a series of competitive reactions and eqailibria, in which tetraboraue is the precursor of pentaborane-11 and hexaborane but not of pentaborane-9 is shown to be compatible with the observed isotope effect. Data obtained by examining the pyrolysis of various mixtures of boron hydrides are also consistent with the mechanism. (auth)

Investigation of the processes controlling the flame generation of refractory materials. Progress report, July 1, 1991--June 30, 1992 (open access)

Investigation of the processes controlling the flame generation of refractory materials. Progress report, July 1, 1991--June 30, 1992

The processes involved in the formation of mixed oxides powders were studied using the counterflow diffusion flame burner. Powders of different morphologies were obtained by varying the flame conditions (temperature, residence time) and the concentration ratio of the oxides precursors. In-situ particle size and number density were determined using dynamic light scattering and 90{degrees} light scattering. A thermophoretic sampling method and a larger scale powder collection device also was used to collect particles, and their size and morphology examined using transmission electron microscopy, X-ray diffraction and surface area measurement by gas absorption (BET). Our emphasis has been on TiO{sub 2}-SiO{sub 2}, SiO{sub 2}-GeO{sub 2} and Al{sub 2}O{sub 3}-TiO{sub 2}. The powders had a core-mantle-like (one oxide coated by the other) at low elevations in the burner and uniform mixture at higher elevations. They form chain-like structures in a low temperature flame and spherical particles in a higher temperature flame. Nanometer sized homogeneous particles of Aluminum Titanate could be obtained using Al(CH{sub 3}){sub 3} and TiCl{sub 4} as precursors both in a hydrogen fueled and a methane fueled counterflow diffusion flame burner, as well as in a hydrogen fueled parallel-flow diffusion flame burner.
