This key text is a major reference work - a totally authoritative handbook on a major current topic. It consolidates state-of-the-art information from the large number of disciplines used in Experimental Fluid Mechanics into a readable desk reference book. It comprises four parts: Experiments in Fluid Mechanics, Measurement of Primary Quantities, Specific Experimental Approaches, and Analyses and Post-Processing of Data. The book has been prepared for physicists and engineers in research and development in universities, in industry and in other research institutions. Both experimental methodology and techniques are covered fundamentally and for a wide range of application fields. A generous use of citations directs the reader to additional material on each subject.
