Introduction to Measurement Techniques
The aim of this Lecture Series is to provide basic knowledge about the measurement techniques currently used in fluid dynamics (pressure & temperature measurements, hot wire, optical techniques incl. Schlieren and shadowgraph method, infrared thermography, spectroscopic measurements, LDV, PIV and signal processing).

Description:
Introduction 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. The director of the course is Professor R.A. van den Braembussche of the von Karman Institute Timetable The course starts on Monday 6 October 2003 at 9h00 and ends on the following Friday at 15h00. Lunch will be taken from 12h05 to 13h45. Coffee break are scheduled each morning and afternoon. General Outline of the Course Components of a measurement chain Measurement uncertainties and errors Transducers active and passive transducers transducers for different applications amplifiers (types and matching) frequency response Pressure measurements static pressure (description and errors) total pressure (probes and errors) flow direction measurements (2 & 3 dimensional) unsteady pressure measurements (frequency response & calibration) Temperature measurements thermocouples surface measurement devices (thin films - liquid crystals) infrared thermography (principles - spatial resolution - quality factor) Hot wire anemometry probe construction and calibration control circuits & linearisation angular response turbulence measurements Optical measurement techniques Laser Doppler Velocimetry (LDV) Particle Image Velocimetry (PIV) Optical density & spectroscopic measurements Flow visualisation air and water flows streamlines and skin friction lines Signal displays, recording & processing oscilloscopes & voltmeters acquisition and recording A/D conversion digital signal acquisition signal processing (frequency analysis,..) The following demonstrations are scheduled on Thursday afternoon and Friday : LDV, PIV & Holographic interferometry Hot wires Infrared thermography Thin film, liquid crystal and thermocouple temperature measurements Steady and unsteady pressure measurements Flow visualisation (watertunnel, schlieren, shadowgraph, oil flow, etc.). Lectures are given by Professors T. Arts, J.-M. Buchlin, M. Carbonaro, O. Chazot, R. D�nos, M. Riethmuller and R.A. Van den Braembussche of the von Karman Institute. Application Form
