AFEF LARIBI : "Soutenance de thèse de Afef LARIBI Confort thermique et optimisation des performances de système solaire passif par simulation numérique"

Abstract : This thesis concerns the study of the thermal performance of a passive solar system of the Trombe wall type via experimental and numerical approaches. The objective is to analyze the impact of the geometric parameters and the composition of the storage wall in different climatic conditions on the thermal behavior of a Trombe wall integrating a room. A state of the art on Trombe walls is carried out in order to identify the indicators allowing the evaluation of their performances and to list the existing experimental and numerical works.
A CFD numerical model is developed to simulate the thermo-aeraulic behavior of a trombe wall system and to evaluate its energy performance. A reduced-scale experimental model is built to be used in the laboratory, in particular for the validation of the CFD model.
Finally, an experimental and numerical parametric analysis is conducted to study the influence of various geometric parameters such as the configuration of the vents, the thickness of the air gap, and the composition of the storage wall on the thermal performance of a Trombe wall system.
The results show that the use of cellular concrete as a storage material and sealed vents ensures the comfort of residents in summer and inter-season conditions. In winter conditions, no significant effect of the thickness of the air gap is noted and the use of reduced-size vents gives the best thermal performance.
