Amélioration Du Transfert Thermique Par Convection Forcée

Résumé: The aim of this thesis is to investigate the improvement of heat transfer during the drying process of the round perforated brick manufactured in Algeria; this investigation requires the examination of its hygrothermal behavior on a macroscopic scale, which we have done through a series of sorption isotherm and hysteresis tests carried out in a well-controlled environment. The aim is to gain a better nderstanding of the macroscopic thermal and hydric properties and the influence of temperature on the behavior of these products based on their microstructure once placed in a given environment. The hygrothermal behavior of the product under consideration is based on the geotechnical study of the soil used for its manufacture. At this stage, we have carried out a variety of analyses to build up an identity card for the raw material used. A good classification of the raw material inevitably leads to a good study of its hygrothermal behavior and, subsequently, to a better optimization of the drying process. A well-dried, well-fired material guarantees a durable, comfortable construction that is resistant to climatic conditions, thus reducing energy consumption and greenhouse gas emissions.
