The objective of this course is to provide young engineers with a broad overview of traditional and advanced measurement techniques applicable to fluid dynamics.
Each measurement technique and its field of application will be described. Limitations and advantages will be discussed and special attention will be given to the subject of error estimation.
A choice of relevant techniques will be demonstrated to groups of five people maximum during lab sessions on Thursday afternoon and Friday in the VKI facilities. This will provide an opportunity to manipulate the available hardware and will allow for discussion of individual problems.This course, prepared and presented by the VKI teaching staff, is based on a long experience with the different techniques for research applications.
Lectures are given by Professors T. Arts, J.-M. Buchlin, M. Carbonaro, O. Chazot, R. Vetrano and Ing. V. van der Haegen of the von Karman Institute. The Director of this course is Professor T. Arts of the von Karman Institute.
