Parallel computing in science and engineering : 4th International DFVLR Seminar on Foundations of Engineering Sciences, Bonn, Federal Republic of Germany, June 25/26, 1987 by Rüdiger Dierstein( Book )

9 editions published in 1988 in English and German and held by 276 WorldCat member libraries worldwide

It was the aim of the conference to present issues in parallel computing to a community of potential engineering/scientific users. An overview of the state-of-the-art in several important research areas is given by leading scientists in their field. The classification question is taken up at various points, ranging from parametric characterizations, communication structure, and memory distribution to control and execution schemes. Central issues in multiprocessing hardware and operation, such as scalability, techniques of overcoming memory latency and synchronization overhead, as well as fault tolerance of communication networks are discussed. The problem of designing and debugging parallel programs in a user-friendly environment is addressed and a number of program transformations for enhancing vectorization and parallelization in a variety of program situations are described. Two different algorithmic techniques for the solution of certain classes of partial differential equations are discussed. The properties of domain-decomposition algorithms and their mapping onto a CRAY-XMP-type architecture are investigated and an overview is given of the merit of various approaches to exploiting the acceleration potential of multigrid methods. Finally, an abstract performance modeling technique for the behavior of applications on parallel and vector architectures is described

Helicopter model rotor-blade vortex interaction impulsive noise : scalability and parametric variations( Book )

1 edition published in 1984 in English and held by 163 WorldCat member libraries worldwide

Acoustic data taken in the anechoic Deutsch-NIederlaendischer Windkanal (DNW) have documented the blade-vortex interaction (BVI) impulsive noise radiated from 1/7-scale model main rotor of the AH-1 series helicopter. Average model-scale data were compared with averaged full-scale, in-flight acoustic data under similar nondimensional test conditions. At low advance ratios (mu = 0.164-0.194), the data scale remarkably well in level and waveform shape, and also duplicate the directivity pattern of BVI impulsive noise. At moderate advance ratios (mu = 0.224-0.270), the scaling deteriorates, suggesting that the model-scale rotor is not adequately simulating the full-scale BVI noise; presently, no proved explanation of this discrepancy exists. Carefully performed parametric variations over a complete matrix of testing conditions have shown that all of the four governing nondimensional parameters -- tip Mach number at hover, advance ratio, local inflow ratio, and thrust coefficient -- are highly sensitive to BVI noise radiation. Keywords: Helicopter noise; Blade vortex interaction; Measured acoustics

Solar thermal energy utilization : German studies on technology and application by Manfred Becker( Book )

The energy crisis in 1973 and 1979 initiated a great number of activities and programs for low and high temperature applica tion of solar energy. Synthetic fuels and chemicals produced by solar energy is one of them, where temperatures in the range of o 600-1000 e or even higher are needed. In principle such high temperatures can be produced in solar towers. For electricity production, the feasibility and operation of solar tower plants has been examined during the SSPS - project (Small Solar Power System) in Almeria, Spain. The objective of Solar Thermal Energy Utilization is to extend the experience from the former SSPS - program in to the field of solar produced synthetic fuels. New materials and technolo gies have to be developed in order to research this goal. Metallic components now in use for solar receivers need to be improved with respect to transient operation or possibly replaced by ceramics. High temperature processes, like steam-methane reforming, coal conversion and hydrogen produc tion need to be developed or at least adapted for the unconven tional solar operation. Therefore Solar Thermal Energy Utiliza tion is a long term program, which needs time for its develop ment much more time than the intervals expected in between further energy crisis. The "Studies on Technology and Applica tion on Solar Energy Utilization" is a npcessary stpp in the right direction in order to prepare for the energy problems in the future
