Résumé
This book will be of great interest to students in Mechanical and Aeronautical Engineering field, professional engineers, university professors and researchers in universities, government and industry. It will also be of interest to all researchers involved in theoretical, computational and experimental methods used in wind turbine design and wind energy development. The book is divided into ten chapters which are presented in a logical manner. The content is easy to follow and each chapter has its own conclusions. The innovative nature of this book is in its comprehensive review of state-of-the-art in VAWTs, correlation of existing knowledge base and the more recent developments in understanding the physics of flow associated with the Darrieus type vertical axis wind turbine. The principal theories and aerodynamic models for performance calculations are presented with experimental data, not only from laboratory measurements but also from real prototypes. The unsteady aerodynamics of Darrieus type VAWTs is dealt with in detail in chapter 5. A CFD model based on the streamfunction-vorticity formulation of the Navier-Stokes equations is presented to study the highlight unsteady effects that may influence design and performance. The real essence of the book is in chapter 6 which provides a practical design model for the Darrieus type VAWTs based on the double-multiple-streamtube model, originally developed by the author. Several software programs (e.g. CARDAAV) for performance calculations are described : several rotor geometries, conventional and natural laminar flow airfoils, dynamic stall effects, secondary effects and stochastic wind model. The subsequent chapters present aerodynamic load and performance data from water channel and wind tunnel experiments, the state-of-the-art innovative aerodynamic devices as applied to VAWTs and the future trends in the design of Darrieus type wind turbine. Finally, chapter 10 deals with the environmental and social aspects of wind energy since it is an emerging environmental technology of great impact and value, and not just a commercial venture.

La simulation de Monte Carlo (Collection méthodes stochastiques appliquées)
La simulation de Monte Carlo est un outil statistique puissant pour résoudre des problèmes mathématiques complexes ou plus exactement pour approcher leur solution aussi précisément que souhaité. Cet ouvrage décrit les principaux problèmes auxquels s'attaque la simulation de Monte Carlo : calcul de sommes ou d'intégrales, d'espérances mathématiques, de problèmes d'optimisation, de résolution d'équations linéaires, intégrales ou différentielles. La simulation de Monte Carlo est illustré de nombreux exemples d'application issus de domaines aussi variés que les télécommunications, la finance, la fiabilité, la physique, etc. Il expose comment les solutions peuvent être approchées et l'erreur analysée via un intervalle de confiance contenant la solution avec une probabilité donnée. Ce livre présente également les différentes techniques d'accélération réduisant l'intervalle de confiance pour un temps de simulation donné. D'autres questions fondamentales sont traitées comme la génération du hasard et des variables aléatoires ou la méthode de simulation de quasi-Monte Carlo qui utilise des suites non aléatoires mais mieux réparties sur le domaine d'échantillonnage, permettant une convergence plus rapide.
