DESHYDRATATION D'ARGILES PAR COMPRESSION ET SECHAGE. ASPECTS DE MODELISATION ET DE SIMULATION

Abstract : This work falls under a general context which is related to the processes of Solid Liquid Separation (SLS) and more particularly to filtration/compression and drying. The objective of this work is to model these two processes by taking in account the mechanical behavior of the studied product. In the first part of work, an experimental characterization of used clays (kaolin and bentonite), in relation with drying, is presented. Then, a thermo-hydro-mechanical general model is developed. The model is then tested in two different cases: one-directionnel and bidirectional situations. The second part of the investigation is devoted to the study and modeling of the processes of filtration/compression. The model developed in this work describes only the phase of compression, and attempts, as previously, to develop a hydro-mechanical model. Simulations resulting from the numerical resolution of the model partly make it possible to validate the undertaken approach.
