Our group has recently developed original approaches and tools that allow to clarify and quantify the internal heat and mass transfers thanks to a proper description of boundary conditions, along with the development of new NMR and MRI techniques [1-4] providing spatially and temporally resolved distributions of the water in its different phases. In parallel, within the framework of the Sense-City equipment, we can use a pilot building insulated with biobased bio-based materials and fully instrumented to follow the temperature and humidity over time.
The objective of this PhD work is, for the first time, to compare the effective behaviour of the building with the predictions of heat and mass transfers through the walls with the help of the detailed intrinsic properties of the materials as determined in the laboratory. The candidate will thus have to carry out an experimental characterization of the materials with the above described tools, set up specific protocols for exploring the hygrothermal behaviour of the room, and use or develop a numerical simulation of this behaviour.
This work will be carried in Laboratoire Navier, within the framework of the ERC Advanced Grant PHYSBIOMAT (2023-2028), in collaboration with the Laboratory CPDM of University Gustave Eiffel. The candidate will thus benefit of a very favorable work environment within groups of research including various students or researchers experts in the different experimental or theoretical aspects of the project, along with all equipments for material characterization.
