On Sept. 7^th, 1998 three pre-seminar courses will be organised (see the programme attached).

• BASIC THERMOGRAPHY

Prof. X. MALDAGUE, Université Laval, Quebec, Canada
Prof. V.L. VAVILOV - Politechnic University, Tomsk, Russia

Principle of infrared thermography, (radiation laws, radiation heat transfer), quantitative thermometry by infrared thermography, (principle, scanner related problems, optical path problems), infrared scanners, cameras and acquisition, deployment applications and data processing, (locking, pulsed thermography, TRIR).

• APPLICATION OF THERMORGAPHY TO THERMOFLUIDDYNAMICS

Prof. G. M. CARLOMAGNO, Universita di Napoli, Napoli, Italy
Prof. G. CARDONE, Universita di Napoli, Napoli, Italy

The course is intended to give to the participants the basic principle of infrared thermography when this is applied to the study of fluid flows. The most practical techniques to be used to perform either surface flow visualization, and/or measurement of convective heat transfer coefficients, will be presented and reviewed. Several applications, which make use of either steady state or transient techniques, will be analyzed and discussed.

• APLICATIONS OF THERMORGAPHY TO SOLIDS

Prof. G. BUSSE, Universität Stuttgart, Germany
Prof. D. ALMOND, Bath University, Bath, UK

Defect imaging using pulsed thermography, reduction in image contrast with defect depth, effects of host material thermal properties, importance of accounting for defect size, numerical modelling. Thermography is suited to monitor fields of infrared emission which are caused by heat deposition from the outside or inside the sample. Therefrom one can derive information related to thermal features of the inspected sample. This is of particular interest for remote nondestructive testing, as will be shown by various examples of the techniques and their applications.

Payment for pre-conference course(s) includes tutorial materials and lunch.
