Full textNumerical tools are commonly used by construction companies to design and validate building systems to meet thermal and environmental requirements of buildings. In the case of solid wood, discrepancies remain between numerical simulations and experimental data regarding moisture transfer. However, their correct consideration is essential to guarantee the durability of wood structures and ensure their thermal performance. This work aims to better understand moisture transfer in solid wood in order to improve the predictive capacity of models. For this purpose, several experimental setups were developed to study the dynamics of moisture transfer in wood samples using X-ray imaging. Firstly, imbibition experiments were conducted to study capillary migration in spruce samples to reproduce exposure of wooden construction components to liquid water during the construction phase. The results – from 3D µCT images – allowed to follow the liquid pathways in the pore network of wood and thus to better understand the effect of anatomy on the water migration. Secondly, the dynamics of moisture transfer under non‑isothermal conditions was studied by applying a sequence of thermal solicitations to the ends of a cylindrical sample similar to the conditions encountered in an external wall. The spatio‑temporal evolution of the moisture content within the sample – initially with a homogeneous moisture content – showed the effect of temperature on the moisture redistribution. Finally, these experimental data were compared with values from numerical simulations in different configurations, illustrating the predictive capacities and limitations of models using a macroscopic formulation to simulate coupled heat-mass transfers in a porous medium

Full textBuilding materials are porous materials, and therefore very sensitive to water. Due to variable hermodynamical ambient conditions, processes of energy and mass transfers between the ambient air and the material occur. These exchanges lead to important modification of their thermal properties and their durability. For instance, measurements of the thermal conductivity of Hemp Lime Concrete, placed in climatic chamber in which the relative humidity is 75%, show a variation of 30%. This PhD Thesis deals with the case of three porous buildin materials: Aerated Autoclaved Concrete (AAC), Hemp Lime Concrete (HLC) and Vertically Perforated Brick (VPB). The hygrothermal behaviour of these materials is studied with the experimental set-up called cell of exchange. This cell consists of test walls which are place between a climatic box and the laboratory. The scope of this experimental work is to create gradients of temperature and of relative humidity through the sample. So, the study aims to measure and characterise heat and mass flows in these materials. Ln a second part, simulation are performed to design, expiain and interpret the experimental results. They are done in COMSOL Multiphysics. Ln a first approach, only the heat equation in 1 D has been implemented in the toolbox. Comparisons between experimental and theoretical results gives us the therm properties of tested materials (ʎ,ρ,c,hs et a). The numerical modeling approach shows that, contrary to AAC or VPB, HLC involves a complex interaction between heat transport and mass transfer through the material. So, simulations on HLC are investigated through the problematic of phase change materials

Full textThe mobilization of arsenic in the environment by naturally occurring processes results in source water contamination. While drinking water represents the main source of exposure to inorganic arsenic, this source water contamination increases the human health hazard. Thus, the maximum contaminant level of arsenic in drinking water was reduced to 10 µg/L and as a consequence new analytical methods and efficient and innovative arsenic removal processes have to be developed and optimized. Here As(III) was quantified by hydride generation atomic absorption spectrometry or by square wave cathodic stripping voltammetry depending on matrix composition. Both chemical and electrochemical processes as coagulation flocculation with Iron(III) salts and electrocoagulation, were optimized to remove arsenic. Their efficiency depends on arsenic speciation, pH, treatment dose and presence of organic matter. These parameters also control the arsenic removal mechanisms

Full textCurrent dynamical models of Solar System formation and geochemical models agree on a likely chondritic origin for the terrestrial water. Indeed, primitive meteorites, called chondrites, have undergone an aqueous alteration process on their parent bodies. Moreover, these meteorites are one of the considered sources for the existence of water in lunar minerals. This thesis lies on hydrogen isotopic ratios and water contents measured using NanoSIMS in the carbonaceous chondrite Paris and lunar soils from the Apollo missions. Chondrules in Paris meteorite seem to have registered a water source distinct from the one of the parent body aqueous alteration. For the moon, water retained in soils is majority formed by implantation of the solar wind hydrogen
