THE ENERGY CRISIS AND NAVAL SHIP RESEARCH AND DEVELOPMENT

Naval Engineers Journal 1974年第3期86卷

作者： CDR. J. RICHARD GAUTHEY USN JOSEPH P. DeTOLLA CDR. J. RICHARD GAUTHEY USN & JOSEPH P. DeTOLLA Cdr. J. Richard Gauthey USN graduated from Cornell University in 1955 with a Bachelor of Mechanical Engineering degree and entered the U.S. Navy through the NROTC program. Following three tours of sea duty he attended the University of California at Berkeley where he earned his Master of Science degree. From 1963 to 1965 he was Project Officer for Aircraft Carriers and Amphibious Ships in the Design Division BUSHIPS. The succeeding three years he was Assistant Repair Superintendent for Surface Ships at the Pearl Harbor Naval Shipyard. After attending the Naval War College he was Maintenance Officer COMINELANT Staff prior to his present assignment as Director Ship Research and Technology Division NAVSHIPS where he has been since 1971. He is a member of both ASNE and SNAME. Joseph P. DeTolla a native of Philadelphia Pa. received his BS degree in Mechanical Engineering from Drexel University in 1969. He began his career with the U.S. Navy in 1965 as a Mechanical Engineering Trainee in the Philidelphia Naval Shipyard Design Division under the BUSHIPS Cooperative Education Training Program. In 1911 he joined NAVSEC as a Mechanical Engineer in the Fluid Systems Branch. For the past two years he has primarily been involved in conducting alternative auxiliary heating system “tradeoff” studies and in the design of total energy/waste heat recovery systems for the PF 109 Class Sea Control Ship DG/AEGIS and AO 177 Class. He is a registered Professional Engineer in the District of Columbia a member of ASE ASME and SNAME and a candidate for the Master of Engineering Administration degree at The George Washington University.

Energy used by U.S. Navy ships is viewed in the context of the national situation. Shipboard usage and the controlling variables are summarized. Research and development being planned by the Navy is described. Efforts relate to conservation of energy as well as consideration of new fuels including hydrogen and liquid hydro-carbon fuels derived from coal, oil shale, and tar sands. A brief account is given of work sponsored by the Department of Interior to produce hydrocarbon fuels, and initial Navy efforts to characterize and evaluate one such fuel is reported. This fuel has been burned at sea in the USS Johnston (DD 821). Development of conservation measures encompasses the utilization of waste heat from gas turbine and diesel engine exhausts and diesel water jackets; more efficient machinery; and reduction of energy requirements. Specific developments discussed include a design methodology to optimize waste heat utilization and higher efficiency gas turbine systems.

Naval Engineers Journal 1973年第4期85卷 82-91页

作者： NEWCOMB, JOHN W. DITRAPANI, ANTHONY R. Mr. John W. Newcomb received his undergraduate education at Webb Institute of Naval Architecture graduating in 1966 and is currently completing requirements for a Master of Business Administration degree at the George Washington University. After gradwlting from Webb he was employed by Texaco Inc. Marine Department and later served three years active duty in the Navy as the DEG-7 Project Oficer at Supervisor of Shipbuilding Conversion and Repair Third Naval District. Subsequent thereto he was employed by the Naval Ship Research and Development Center prior to assuming his present position in the Ship System Design Division of the Naval Ship Engineering Center. He is a member of ASNE and SNAME. Mr. Anthony R. Di'hapani received his BS degree in Mechanical Engineering from the University of Wisconsin in 1958 and subsequently completed course requirements for a Master of Engineering Science while an evening student at the George Washington University. He began his engineering career in 1958 in the BuShips Steam Turbine and Gear Branch specializing in steam turbine systems for nuclear submarines. In 1962 after completing a Navy-sponsored Electronics Training Program he joined the SQS-26 Sonar Project and served as Head of the Special Projects Section and subsequently the Test and Analysis Section until selected in 1967 to head the ASW Branch for the newly-churtered DXIDXG Project now the DO963 Ship Acquisition Project in the Naval Ship System Command. In 1970 he was designated a8 Acting Director of the DD963 Technical Management Plans Division and when the PF Program emerged in 1971 was reassigned as Deputy Project Manager for the Patrol Frigate Project.

Late in 1970, Admiral E. R. Zumwdt, Chid of Naval Operations, directed that study begin towards development of a new class of ocean escort to be known BS Patrol Frigate (PF) to take over some of the duties of the Navy's World War II destroyers as these 25 year old ships are retired from the active Fleet. At the same time, the Department of Defense, was significantly revising its basic policies for the development and acquisition of major weapons systems, and PF became the Nay's first major ship claw acquisition under these new policies. This new requirement, as atmound in DOD Directive 5000.1, along with the program constraints imposed by the CNO, required the development of a philosophy and approach towards design, test and evaluation and acquisition which was significantly Merent from ship procurements of the recent past. This paper disc the overall acquisition proms for the Patrol Frigate Class BS it is being developed and implemented to meet these needs and constraints, and provides a commepfary regarding the effectiveness of the appraach as of January 1973. © 1973 by the American Society of Naval Engineers

The magnetic entropy behavior has been analyzed in the double-perovskite Ba2-xLaxFeMoO6 ( x}=0, 0.1, 0.2) compound with the sintering temperature. Samples were fabricated by conventional solid-state reaction method. The results show that the values of Δ SM are increased with increasing sintering temperature from 1273 K to 1473 K. The values of ΔSM for Ba2-xLaxFeMoO 6(x = 0) are increased about five × with increasing sintering temperature, especially. The enhancement of the magnetic entropy change is believed to be due to a strong coupling between spin and lattice in the magnetic transition process near Curie temperature. Our result reveals that the proper sintering of perovskite Ba2-xLaxFeMoO6 compound makes it one of the useful methods for the development of advanced magnetic refrigeration materials. © 2006 IEEE.

The present-day state and future of the Antarctic Ice Sheet depend on the rate at which the ocean melts its fringing ice shelves. Ocean heat must cross many physical and dynamical barriers to melt ice shelves, with the last of these being the ice–ocean boundary layer. This review summarizes the current understanding of ice–ocean boundary-layer dynamics, focusing on recent progress from laboratory experiments, turbulence-resolving numerical simulations, novel observations, and the application to large-scale simulations. The complex interplay between buoyant meltwater and external processes such as current shear leads to the emergence of several melting regimes that we describe, as well as freezing processes. The remaining challenges include developing new parameterizations for large-scale ice–ocean models based on recent advances and understanding the coevolution of melt and basal topography.

Environment and Resources 1000年第1期42卷 289-316页

作者： Jeffery B. Greenblatt Nicholas R. Brown Rachel Slaybaugh Theresa Wilks Emma Stewart Sean T. McCoy 1Energy Analysis and Environmental Impacts Division Lawrence Berkeley National Laboratory Berkeley California 94720 email: jbgreenblatt@lbl.gov 2Department of Mechanical and Nuclear Engineering Pennsylvania State University University Park Pennsylvania 16802 3Department of Nuclear Engineering University of California Berkeley California 94720 4Plasma Science and Fusion Center Massachusetts Institute of Technology Cambridge Massachusetts 02139 5Lawrence Livermore National Laboratory Livermore California 94550 6Global Security E Program Lawrence Livermore National Laboratory Livermore California 94550

We review future global demand for electricity and major technologies positioned to supply it with minimal greenhouse gas (GHG) emissions: renewables (wind, solar, water, geothermal, and biomass), nuclear fission, and fossil power with CO2 capture and sequestration. We discuss two breakthrough technologies (space solar power and nuclear fusion) as exciting but uncertain additional options for low-net GHG emissions (i.e., low-carbon) electricity generation. In addition, we discuss grid integration technologies (monitoring and forecasting of transmission and distribution systems, demand-side load management, energy storage, and load balancing with low-carbon fuel substitutes). For each topic, recent historical trends and future prospects are reviewed, along with technical challenges, costs, and other issues as appropriate. Although no technology represents an ideal solution, their strengths can be enhanced by deployment in combination, along with grid integration that forms a critical set of enabling technologies to assure a reliable and robust future low-carbon electricity system.
