Advanced School : Thermal Measurements & Inverse Techniques 7th edition (METTI 7)

PROCEEDINGS

Foreword: Finding ‘causes’ from measured ‘consequences’ using a mathematical model linking the two is an inverse problem. This is met in different areas of physical sciences, especially in Heat Transfer. Techniques for solving inverse problems as well as their applications may seem quite obscure for newcomers to the field. Experimentalists desiring to go beyond traditional data processing techniques for estimating the parameters of a model with the maximum accuracy feel often ill prepared in front of inverse techniques.

 In order to avoid biases at different levels of this kind of involved task, it seems compulsory that specialists of measurement inversion techniques, modelling techniques and experimental techniques share a wide common culture and language. These exchanges are necessary to take into account the difficulties associated to all these fields. It is in this state of mind that this school is proposed.

The METTI Group (Thermal Measurements and Inverse Techniques), which is a division of the French Heat Transfer Society (SFT), has already run or co- organized six similar schools, in the Alps (Aussois, 1995 and 2005), in the Pyrenees (Bolquère-Odeillo, 1999), in Brasil (Rio de Janeiro, 2009), in Bretagne (Roscoff, 2011) and in Pays Basque (Biarritz, 2015). The seventh edition of the school was again open to participants from all over the world with the support of the Eurotherm Committee.

NB: The next edition of this school, Metti 8, will take place from Sept. 24 to 29, 2023 in the “Ile d’Oléron” in  France, see https://metti8.sciencesconf.org/
