Non-destructive evaluation (NDE) method has been popularly used for thermal diagnosis of building envelop in order to retrofit old buildings, detect civil engineering structures and accredit new buildings. The infrared thermography technique has been widely applied in the NDE method. In order to develop new solutions for diagnostic of local thermal performance, experiments were carried out on two cases of multi-layer walls. Experimental results of emissivity, temperature, and heat fluxes will be shown and analyzed in this article. The main originality of this work is to try to compute the front face temperature response to transient periodic heating by computing the front face pulse response. Such front face pulse response is obtained by a deconvolution method and a TSVD inverse method. The thermal properties of the wall will be characterized through the opotimization method based on the thermal quadrupoles model.

Mesure de cartographies de teneur en eau par imagerie térahertz

Alain Sommier; Christophe Pradere; Hocine Boutaleb; Laura Rodriguez; Denis Bruneau; Jean-Rodolphe Puiggali; Jean-Christophe Batsale

RÉSUMÉ. Cette étude présente une méthode d’imagerie multispectrale Terahertz (THz) permettant la mesure de teneur en eau dans des milieu poreux . Le système TH z est décrit tout comme la méthode de calibration de teneur en eau. La précision de cette technique expérimentale est démontrée en comparant la mesure de profils de teneur en eau en fonction du temps dans de la cellulose et les profils théorique obtenus par un modèle de séchage 1D. Enfin nous présentons les mesures réalisées lors du séchage de pin maritime.
