TRANSCRIPT
Springer Handbookof Experimental Fluid Mechanics
Springer Handbooks providea concise compilation of approvedkey information on methods ofresearch, general principles, andfunctional relationships in physi-cal sciences and engineering. Theworld’s leading experts in the fieldsof physics and engineering will beassigned by one or several renownededitors to write the chapters com-prising each volume. The contentis selected by these experts fromSpringer sources (books, journals,online content) and other systematicand approved recent publications ofphysical and technical information.
The volumes are designed to beuseful as readable desk referencebooks to give a fast and comprehen-sive overview and easy retrieval ofessential reliable key information,including tables, graphs, and bibli-ographies. References to extensivesources are provided.

The purpose of this Springer Handbook is to provide comprehensive support to theexperimental fluid mechanics community, for planning, executing, and interpretingexperiments. This purpose is addressed by organizing the handbook into four parts:Part A (Chaps. 1 and 2) addresses the motivation for experiments and the equationsthat build the foundations for experimental work; Part B (Chaps. 3–8) examines themeasurement of, and measurement techniques used for, all primary quantities appearingexplicitly in the governing equations; Part C (Chaps. 9–21) presents topics related toa specific application area or technique and; Part D (Chaps. 22–25) is meant to serveas a reference in questions regarding signal and data acquisition and processing.
Experimental fluid mechanics comprises a very large number of topics and specialapplication areas and in undertaking such a handbook project a selection must necessar-ily be made. In making this selection the editors have attempted to cover as completelyas possible the most fundamental concepts and most frequently employed measure-ment techniques and fluid behaviors. Those topics that have not been included in thisfirst edition will perhaps find a place in a future edition.
The editors of this Springer Handbook would like to heartily thank the contributingauthors, who have all captured the spirit of this handbook and made significant improve-ments to our original concept. Furthermore, a special thanks goes to Dr. Werner Skolautat Springer for his untiring efforts in assembling the final version of all the manuscriptsand coordinating the production process. And finally, thanks go to Ms. Claudia Rauand her team at LE-TeX Jelonek, Schmidt & Vöckler GbR for their skillful preparationof manuscripts into final production form.
Inevitably there will be misprints in this handbook and readers are invited to bringthese to the attention of the Editors via e-mail. Similarly, suggestions for improvementsin a second edition are also very welcome.

Nomenclature
Experimental fluid mechanics draws on numerous dis-ciplines in addition to fluid mechanics itself: rheology,physics, electromagnetic theory, optics, electronics, sig-nal processing, data processing, etc. Each disciplineand community has developed its own nomenclatureand conventions and inevitably there exist many con-flicting designations when one attempts to assembleall of these conventions into one handbook. There-fore, we have instructed authors to adhere as closelyas possible to the skeleton nomenclature given belowand to note explicitly in their respective articles any
deviations or extensions thereof. Authors of articlesdealing with constitutive equations, material proper-ties and non-Newtonian flows were asked to follow, asfar as possible, the nomenclature given in J.M. Dealy:Official nomenclature for material functions describ-ing the response of a viscoelastic fluid to variousshearing and extensional deformations, J. Rheol. 39(1),253–265 (1995). Furthermore, all authors were askedto prepare their manuscripts using SI units, a reviewof which is provided below, following the nomencla-ture.
