Flow Control and Optimization is increasingly incorporated in the design of engineering devices ranging from aircraft and space vehicles to microfluidic devices. Research in this field aims to integrate knowledge in flow physics with theoretical advances and novel experimental capabilities and engineering devices capable of materializing advanced design concepts. In turn controlled flow phenomena exhibit a new arrays of physics and open frontiers for further interdisciplinary research in fluid mechanics and all the engineering domains that it affects. This collection of papers in flow control, showcases representatives lines of work in the area of flow control demonstrating the interdisciplinary character and high scientific merit of this field. The authors of these articles are among the pioneering researchers in this field and continue to explore the frontiers in flow control and optimization. We hope that this volume, while largely representing work by the authors prior to 2004, contributes in providing an authoritative report on this rapidly changing field.

These Lecture Series in Computational Science and Engineering include the proceedings of a Summer Program in Multi-Scale Modelling and Simulation held in Lugano, Switzerland, between August 4th and 30th, 2003. The workshop was organized by the ETHZ Computational Laboratory (CoLab) together with the Swiss Center for Scientific Computing in Manno (CSCS) and the Universit della Svizzera Italiana (USI) in the context of the ETHZ initiative in Computational Science and Engineering. Computational Science and Engineering entails interdisciplinary research, by a sustained interaction of a critical mass of researchers, tackling complex problems of scientific and engineering interest under the unifying concept of computation. Multiscale modeling and Simulationsis a fundamental research topic in CSE exemplifying its interdisciplinary aspects and its unique character as a scientific discipline. A broad range of scientific and engineering problems involve multi-scale phenomena. The computational study of these problems demands an ever increasing development of novel computational tools and mathematical methods. This Summer Program provided the opportunity to scientists from different scientific fields, faced with multiscaling problems, to exchange ideas and to pursue research in an interdisciplinary fashion. The workshop strengthened existing collaborations and developed new contacts between the participants that we believe will help in defining new scientific frontiers. The scientific interactions, the weekly lectures and the working sessions showed that scientific cross fertilization can lead to significant advances in the specialized fields as well as in the unifying computational methodologies. The proceedings of this workshop serve as an attestation of this spirit of interdisciplinarity that characterises research in multiscale modeling and simulation.

Some words about SCART 2000. SCART stands for science and art. SCART meetings are organized in a loose time sequence by an international group of scientists, most of them fluid-dynamicists. The first meeting was held in Hong-Kong, the second one in Berlin, and the third, and latest, one in Zurich. SCART meetings include a scientific conference and a number of art events. The intention is to restart a dialogue between scientists and artists which was so productive in the past. To achieve this goal several lectures given by scientists at the conference are intended for a broader public. In the proceedings they are denoted as SCART lectures. The artists in tum address the main theme of the conference with their contributions. The lectures at SCART 2000 covered the entire field of fluiddynamics, from laminar flows in biological systems to astrophysical events, such as the explosion of a neutron star. The main exhibition by Dutch and Swiss artists showed video and related art under the title ‘Walking on Air’. Experimental music was performed in two concerts. Video and related art was chosen because this medium of expression is very technical and closely related to science and technology. In addition, a common aspect of this kind of art and science is the dimension of time. New ways of possible creative processes were shown with music. The ear decomposes sound by a Fourier analysis, the brain therefore interprets sound in a phase space, whereas images are seen in an analogous form in a physical space. These two impressions are analyzed in two different processing centers in the brain, and it is more than a philosophical question whether we need both types of information to get a reliable grasp of reality. Such ideas were also discussed in two seminars organized by the Collegium Helveticum during the conference. In the proceedings all those interactions cannot be shown, but we hope to transmit a flavor of the interdisciplinary effort, which could stimulate the creativity of the reader as well. Some words about these proceedings. These proceedings contain the scientific contributions, ordered by themes, as they were presented at the conference. To show the close relation between science and art, the proceedings also contain the art part which is reproduced as a catalogue of the exhibition. This part is edited by Nadia Gyr, the curator of the exhibition. Due to this concept and due to the esthetic aspects of many scientific contributions, this book contains a rather extensive representation in colors, 32 pages. It is the hope of the editors, that this book helps in stimulating the dialog between science and art, and that it may also contribute to the continuation of such common efforts.

Vortex methods have matured in recent years, offering an interesting alternative to finite difference and spectral methods for high resolution numerical solutions of the Navier Stokes equations. In the past three decades, research into the numerical analysis aspects of vortex methods has provided a solid mathematical background for understanding the accuracy and stability of the method. At the same time vortex methods retain their appealing physical character, which was the motivation for their introduction. This book presents and analyzes vortex methods as a tool for the direct numerical simulation of impressible viscous flows. It will interest graduate students and researchers in numerical analysis and fluid mechanics and also serve as an ideal textbook for courses in fluid dynamics.
