For rather a long time numerical results in chemical kinetics could only be obtained for very simple chemical reactions, most of which were of minor practi ca 1 importance. The avail abil ity of fast computers has provi ded new opportunities for developments in chemical kinetics. Chemical systems of practical interest are usually very complicated. They consi st of a great number of different el ementary chemi cal reacti ons, mostly with rate constants differi ng by many orders of magni tude, frequently with surface reacti on steps and often wi th transport processes. The deri vati on of a 'true' chemical mechani sm can be extremely cumbersome. Mostly this work is done by setting up 'reaction models' which are im proved step by step in comparison with precise experimental data. At this early stage mathematics is involved, which may al ready be rather complicated. Mathematical methods such as pertubation theory, graph theory, sensitivity analysis or numerical integration are necessary for the derivation and application of optimal chemical reaction models. Most theoretical work aimed at improving the mathematical methods was done on chemical reactions which mostly were of little practical im portance. Chemi cal engi neers, who evi dently k now well how important the chemical model s and their dynamics are for reactor desi gn, have al so to be convinced not only on the theoretical work but also on its practical applic abil ity
Mathematics, key technology for the future : joint projects between universities and industry by W Jäger( Book )

18 editions published between 2003 and 2013 in English and German and held by 235 WorldCat member libraries worldwide

This book is about the results of a number of projects funded by the BMBF in the initiative "Mathematics for Innovations in Industry and Services". It shows that a broad spectrum of analytical and numerical mathematical methods and programming techniques are used to solve a lot of different specific industrial or services problems. The main focus is on the fact that the mathematics used is not usually standard mathematics or black box mathematics but is specifically developed for specific industrial or services problems. Mathematics is more than a tool box or an ancilarry science for other scientific disciplines or users. Through this book the reader will gain insight into the details of mathematical modeling and numerical simulation for a lot of industrial applications

Reactive flows, diffusion and transport : from experiments via mathematical modeling to numerical simulation and optimization : final report of SFB (Collaborative Research Center) 359 by Willi Jäger( Book )

6 editions published in 2007 in English and held by 129 WorldCat member libraries worldwide

The articles in this volume summarize the research results obtained in the former SFB 359 "Reactive Flow, Diffusion and Transport" which has been supported by the DFG over the period 1993-2004. The main subjects are physical-chemical processes sharing the difficulty of interacting diffusion, transport and reaction which cannot be considered separately. Typical examples are the chemical processes in flow reactors and in the catalytic combustion at surfaces. Further examples are models of star formation including diffusive mass transport, energy radiation and dust formation and the polluting transport in soil and waters. For these complex processes mathematical models are established and numerically simulated. The modeling uses multiscale techniques for nonlinear differential equations while for the numerical simulation and optimization goal-oriented mesh and model adaptivity, multigrid techniques and advanced Newton-type methods are developed combined with parallelization. This modeling and simulation is accompanied by experiments

It also reflects the changes in organization and focus of the center which are briefly described here. In 2003 HLRS has teamed up with the University of Karlsruhe in the Competence Center for High Performance Computers of the State of Baden-Wiirttemberg (hkz-bw). This cooperation was gradually deployed during 2004 and has helped to im prove the basic services. With an extension of the cooperation to other uni versities HLRS aims at further strengthening its ties with researchers in the State of Baden-Wiirttemberg. Users should beneflt from such a larger pool of expertise and the transformation of basic research into simulation results should be improved

The last two years have been great for high performance computing in Baden- W{u00A8} urttemberg and beyond. In July 2005, the new building for HLRS as well as Stuttgart{u2019}s new NEC supercomputer {u2013} which is still leading edge in G- many {u2013} have been inaugurated. In these days, the SSC Karlsruhe is?nalizing the installation of a very large high performance system complex from HP, built from hundreds of Intel Itanium processors and more than three th- sand AMD Opteron cores. Additionally, the fast network connection {u2013} with a bandwidth of 40Gbit/s and thus one of the?rst installations of this kind in Germany {u2013} brings the machine rooms of HLRS and SSC Karlsruhe very close together. With the investment of more than 60 Million Euro, we {u2013} as the users of such a valuable infrastructure {u2013} are not only thankful to science managers and politicians, but also to the people running these components as part of their daily business, on a 24-7 level. Sinceabout18months, therearelotsofactivitiesonallscienti?c, advisory, and political levels to decide if Germany will install an even larger European supercomputer, where the hardware costs alone will be around 200 Million Euro for a?ve year period. There are many good reasons to invest in such a program because {u2013} beyond the infrastructure {u2013} such a scienti?c research tool will attract the best brains to tackle the problems related to the software and methodology challenges
Der Heidelberger Karl-Theodor-Globus von 1751 bis 2000 : Vergangenes mit gegenwärtigen Methoden für die Zukunft bewahren by Willi Jäger( Book )

1 edition published in 2004 in German and held by 49 WorldCat member libraries worldwide

Ein gelungenes Beispiel für eine lebendige Zusammenarbeit mit unterschiedlichen Disziplinen wird mit der Restauration dieses wichtigen Kulturguts veranschaulicht: Das Heidelberger Exemplar eines Vaugondy Globus von 1751 hat eine wechselvolle Geschichte und wurde in jüngster Zeit mit hochmodernen Methoden aufwendig restauriert. Historische Quellen über die Art der Herstellung von Globen wurden ebenso zu Rate gezogen wie moderne mathematische Verfahren aus der Bildverarbeitung, mit denen die digitalisierte Weltkarte gefiltert wurde. In der Auseinandersetzung mit historischen Aspekten gelang darüber hinaus ein Einblick in die Bedeutung von Globen und das Entstehen eines neuen Weltbildes im 18. Jahrhundert, das mit den wissenschaftlichen Akademien einherging
