Amélioration du transfert thermique par convection forcée

Abstract

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.
