Fluid Mechanics in France in the First Half of the Twentieth Century

If one opens today a textbook on fluid mechanics, it seems that whereas French scientists of the eighteenth and nineteenth centuries are frequently mentioned, those from more recent times occur rarely; in particular, French contributions to the major breakthroughs of the first half of the twentieth century (boundary layers and turbulence) would appear quite modest. However, study of contemporary documents (PhD theses, journals, correspondence, etc.) reveals remarkable work undertaken by outstanding personalities. A key instigator of these achievements was the French Air Ministry, which, starting in 1929, and with great open-mindedness, created and generously financed four Institutes of Fluid Mechanics and five teaching centers in faculties of science. This reveals the 1930s in their true light as a fruitful decade, with achievements that explain the prominent role played by France in the creation of the International Union of Theoretical and Applied Mechanics (IUTAM) in 1946. This review recounts the story of fluid mechanics in France, with emphasis on the connection between scientific questions and social and cultural issues, in a period marked by two world wars and great strengthening of international relationships.

Preface for the thematic issue: IMSD 2012

The Second Joint International Conference on Multibody System Dynamics (IMSD 2012) was held May 29 to June 1, 2012 at the University of Stuttgart, Germany. It served as a meeting point for the international multibody community and provided an opportunity to exchange high-level, current information on the theory and applications of multibody systems. As a rapidly growing branch of mechanics, multibody system dynamics is seeing more and more use, and is becoming increasingly important in the development of complex engineering systems. The continual new challenges faced by the IMSD community demand productive exchange of ideas and a spirit of cooperation is encouraged. The conference was attended by 301 participants from 29 countries and 199 talks were delivered. Institutional sponsors of the IMSD are the ASME (American Society of Mechanical Engineers), IFToMM (International Federation for the Promotion of Mechanism and Machine Science), IUTAM (International Union of Theoretical and Applied Mechanics), JSME (Japanese Society of Mechanical Engineers), KSME (Korean Society of Mechanical Engineers). Based on recommendations of the members of the Scientific Committee and the Session Organizers, authors giving insight into advanced topics of recent multibody dynamics were invited to submit papers. All these papers have been strictly peer-reviewed to guarantee high quality and a good representation of various fields of multibody dynamics. The papers now published in this Thematic Issue are selected, among those accepted, in order to represent the most recent challenges and developments in Multibody Dynamics in its various fields. We wish you a most interesting reading.

Preface to the special issue on physical mechanics

The 23rd International Congress of Theoretical and Applied Mechanics (ICTAM2012) will be held in Beijing, China, from August 19 to 24, 2012. The Congress (ICTAM), as the most authoritative and comprehensive conference in mechanics in the world and regarded as the “Olympic games” of mechanicians, is organized by the International Union of Theoretical and Applied Mechanics (IUTAM) every four years. It brings together scientists and students from all over the world to exchange state-of-the-art achievements in the field of mechanics to promote the research, application and education of mechanics. The ICTAM2012, hosted by the Chinese Society of Theoretical and Applied Mechanics (CSTAM), is expected to promote research and applications of mechanics in China as well as throughout the world. CSTAM has decided to launch a series of activities in 2012 named “Mechanics Year 2012”, with the theme of “Mechanics · Achievement · Future”.

Preface for the special issue: IMSD

The First Joint International Conference on Multibody System Dynamics (IMSD2010), held in May 2010 at the Lappeenranta University of Technology (LUT) in Finland, enabled the international multibody community to meet and exchange information and ideas on the theory and applications of multibody systems. It was sponsored by the ASME (American Society of Mechanical Engineers), IFToMM (International Federation for the Promotion of Mechanism and Machine Science), IUTAM (International Union of Theoretical and Applied Mechanics), KSME (Korean Society of Mechanical Engineers), and JSME (Japan Society of Mechanical Engineers). The conference, attended by 242 participants, featured more than 180 presentations, delivered by representatives of 29 countries. In view of the exceptional works presented and the discussions that followed, which included many of the foremost international researchers in Multibody Dynamics, a selected number of authors were invited to submit manuscripts to the Multibody Systems Dynamics journal where they have undergone a strict peer-review process. This issue of the Multibody Systems Dynamics journal presents six of these papers representing the range of topics addressed by Multibody Dynamics; vehicle dynamics, control and mechatronics, algorithms, integration codes, and software. These manuscripts suggest a trend towards theoretically and computationally challenging applications. We are confident that journal readers will find the contents of this issue informative and valuable in their activities related to multibody systems. We would like to take this opportunity to thank the sponsors, organizers, and all participants of the IMSD2010 conference. The success of this First Joint International Conference on Multibody System Dynamics would not have been possible without

Turbulence before Marseille 1961

The surge of turbulence research in the first half of the twentieth century is reviewed with the focus on the institutional environment that provided an umbrella for the activities in this field. Before the Second World War, the International Congresses for Applied Mechanics served as the main stage for presenting research results on turbulence. After the War, the International Union of Theoretical and Applied Mechanics (IUTAM), organizations such as the Division of Fluid Dynamics of the American Physical Society and new journals (the Journal of Fluid Mechanicsand The Physics of Fluids) added to the institutional framework for turbulence activities and publications. The development of these activities is illustrated with examples from the correspondence of some of the involved actors (such as George K. Batchelor and Francois N. Frenkiel, the editors of the new journals; both were also involved with the organization of the Marseille events in 1961).

Simulation and Identification of Organized Structures in Flows. Edited by J. N. SORENSEN, E. J. HOPFINGER & N. AUBRY. Kluwer, 1999. 515 pp. ISBN 0 7923 56039. NLG 395 or US$237 or £104.

This book is the Proceedings of the IUTAM Symposium on ‘‘Simulation and Identification of Organised Structures in Flows,’’ held in Lyngby, Denmark, May 25‐29, 1997. The symposium was one of those specialized symposia in the field of mechanics that the International Union of Theoretical and Applied Mechanics (IUTAM) organizes every year. The IUTAM Symposia are normally reserved to invited participants, and usually provide the state-of-the-art assessment of a particular problem by leading professionals. This book is no exception. It presents a useful overview of organized structures in fluid mechanical applications. It covers a wider range of issues than did a previous Symposium on a similar topic held in October 1992 in Poitiers, France. Selected papers from that Symposium—‘‘Eddy Structure Identification in Free Turbulent Shear Flows’’—were published in a Proceedings edited by J. P. Bonnet and M. N. Glauser (1993). Information on organized structures in flows and their interactions with flow boundaries is of considerable hydraulic engineering importance. For instance, work underway at New Zealand’s National Institute of Water and Atmospheric Research (NIWA) on periphyton (attached aquatic microalgae) interactions with turbulence is revealing significant mechanisms of mass transfer in the near-bed region. Such mechanisms appear to influence periphyton growth and losses. ADV measurements of turbulence in the NIWA outdoor ecohydraulics flume (Fig. 1) show that the appearance of periphyton on a cobble bed does not change appreciably the velocity spectra above the cobble. However, its appearance reduces the total spectral energy and generates a wide spectral peak in the region below cobble tops. Most probably, this peak is formed by penetration of sweep events into that region, ‘‘filtered’’ by the periphyton tufts. Thus, organized structures may be the main mechanism responsible for the delivery of nutrients from the outer region to the biologically active near-bed layer.

First Symposium on Nonhomogeneity in Elasticity and Plasticity

The first Symposium on Nonhomogeneity in Elasticity and Plasticity was held in Warsaw, Poland, from the 2nd to the 8th of September. It was the first meeting in Poland sponsored by IUTAM (the International Union of Theoretical and Applied Mechanics) and our hosts, led by W. Olszak, spared no effort to make the occasion both memorable and pleasant. Social events and sightseeing trips interlaced and surrounded the very full technical program. From the time of personal greeting upon our arrival at the airport to the time of waved goodbyes, help and advice were available instantly if needed. On the other hand, we were completely free to look around on our own and to visit any place we pleased by foot or by taxi.
