Etude expérimentale et modélisation physique des transferts couplés chaleur-humidité dans un isolant bio-sourcé. / Experimental study and physical modeling of simultaneous heat and moisture transfer in bio-sourced insulating materials.Aghahadi, Mohammad 29 May 2019 (has links)
Le caractère fortement hydrophile des isolants thermiques bio-sourcés, a montré que les modèles classiques de transfert thermique ne sont pas suffisamment adaptés pour leur caractérisation thermique. Ce travail de thèse vise à répondre à cette problématique par des approches expérimentale et théorique des transferts couplés chaleur-humidité. Dans l’approche expérimentale, un isolant thermique en feutre de fibres de lin (FFL) a été développé puis caractérisé, dans différents états hygrométriques, au moyen d’un dispositif Plan Chaud asymétrique. Des isothermes d’adsorption de l’humidité corrélés aux modèles théoriques GAB, GDW et Park permettent une caractérisation hydrique de cet isolant. Dans l’approche théorique, un modèle physique, de transfert couplé chaleur-humidité au sein de l’isolant FFL humide, est proposé. Il est résolu numériquement, en configuration 3D transitoire, par la méthode de éléments finis sous COMSOL Multiphysics et par la méthode des différences finies, en configuration 1D transitoire, sous MATLAB. La méthode de Levenberg-Marquardt couplée avec le modèle direct 1D transitoire et les températures mesurées a permis d’estimer la conductivité thermique apparente de l'échantillon étudié avec une erreur relative inférieure à 6% par rapport aux mesures expérimentales, validant ainsi les modèles théoriques. / The conventional heat transfer models are not sufficiently suitable for thermal characterization of bio-sourced thermal insulating materials due to their strongly hydrophilic nature. The proposed work in this PhD thesis aims to answer this problem with experimental and theoretical approaches of coupled heat-moisture transfers. In the experimental approach, a thermal insulating material based on Flax Fiber Felt (FFF) is developed and then characterized at different hygrometric conditions with an asymmetric hot plate device. The humidity diffusion characterization of the samples is done using the GAB, GDW and Park theoretical moisture adsorption isotherm models. In the theoretical approach, a physical model of heat and mass transfer is proposed. It is solved numerically, in transient 3D configuration, by the finite element method under COMSOL Multiphysics and, in transient 1D configuration, by the finite difference method under MATLAB. The Levenberg-Marquardt method coupled with the 1D transient direct model and the measured temperatures made it possible to estimate the apparent thermal conductivity of the studied sample with a relative error of less than 6% compared to the experimental measurements, thus validating the theoretical models.
