"Laser Techniques for Fluid Mechanics" is a technical book that addresses the latest developments and applications of laser techniques in fluid mechanics. It is based on the revised and expanded versions of selected contributions presented at the tenth International Symposium on this topic. The event took place in 2000 in Lisbon and served as a platform for the exchange of advanced research and innovative methods for flow measurement. The works included in this volume cover a wide range of topics, including instrumentation developments for velocity, scalar, and multiphase flows, as well as measurements of turbulent flows, combustion, and engines. The book is aimed at professionals and students interested in the theoretical and practical aspects of laser methods in fluid mechanics and provides valuable insights into the latest advancements in this dynamic research field.
