Etude du comportement rhéologique de mélanges argiles-polymères : Effets de l'ajout de polymères by Adel Benchabane( Book )

The aim of the present work is to establish a bibliographical synthesis on the microstructure, the colloidal and rheological characterization of bentonite suspensions with and without polymer/surfactant addition; to lead to a rheological characterization of clay-additive mixtures and to understand the interaction between the clay particles and polymer/surfactants. Different experimental measurements: rheology, particle sizing, and x-ray diffraction were used to study the rheological character of the water-bentonite-anionic additive mixtures (CMC, SDS, xanthane) as well as the nature of the particle-particle interactions and particle-additive. The modeling part led to the adoption of Tiu and Boger's model to predict the thixotropy of the bentonite suspensions without additive. Thus, a new model is proposed with physical parameters for a better correlation of the rheological behavior of the various studied mixtures
Thermal design of Earth-to-Air Heat Exchanger. Part I a new transient semi-analytical model for determining soil temperature( )

Abstract: This article is the first in a series about the thermal design of Earth-to-Air Heat Exchanger, EAHE, using a new developed semi-analytical method. The temperature distribution in the soil surrounding the EAHE is studied in the goal to determine the soil radius as a function of the operation duration. This radius is the first distance from the pipe axis where there is no effect of heat from EAHE. For that, a new transient semi-analytical model is developed in particular to facilitate the thermal design of EAHEs. The main application of the developed model is to predict the deterioration in EAHE's thermal performance as a function of the duration operation. This deterioration can be caused by soil thermal saturation where the nearby subsoil temperature becomes almost equal to the inlet air temperature resulting in minimum heat transfer between air and soil. The analytical solution of the proposed model has been integrated by means of the Bessel function method, for a constant heat flux per unit of length at the pipe surface in the radial dimension and constant inlet air temperature. The model has been verified with several results obtained from the literature. In addition, an investigation of continuous operation of an EAHE is made on thermal performance of the EAHE in the soil of the region of Biskra (Southern Algeria) (34°472 - 005°432) by applying extreme ambient air temperature (57°C). Results show that the deterioration in thermal performance of EAHE is observed for longer duration in hot and dry climate. In the case of 6h of continuous operation, the soil radius can reach 0.55m from the pipe surface. The model proposed in this paper can be considered as the first of its kind which gives a formula for calculating the soil radius (thickness) as a function of the: i) duration of operation, ii) soil thermal diffusivity, iii) pipe diameter and iv) air temperature. Highlights: New transient semi-analytical model, named RBM model, is presented and verified. Application example of the RBM model in Biskra (Algeria) is illustrated. RBM model is used for the thermal design of Earth-to-Air Heat Exchanger, EAHE. RBM model predicts the deterioration in EAHE's thermal performance. RBM model estimates the soil radius as a function of time and soil/air properties
Etude du comportement rhéologique de mélanges argiles-polymères Effets de l'ajout de polymères by Adel Benchabane( )

1 edition published in 2007 in French and held by 1 WorldCat member library worldwide

L'objectif de ce travail est d'établir une synthèse bibliographique sur la microstructure, la caractérisation colloïdale et rhéologique des suspensions de bentonite sans et avec l'ajout de polymères/tensioactifs ; d'aboutir à une caractérisation des propriétés rhéologiques de complexes argile-additif et de comprendre les mécanismes d'interactions entre les feuillets d'argile et le polymère. Les mesures rhéologiques, granulométriques et de diffraction par rayons X ont contribué à la compréhension du caractère rhéologique des mélanges eau-bentonite-polymères anioniques (CMC, SDS, xanthane) ainsi que la nature des interactions particule-particule et particule-additif. La partie modélisation a abouti à l'adoption du modèle de Tiu et Boger pour modéliser la thixotropie des suspensions de bentonite sans additif. Ainsi, un modèle original, avec des paramètres physiques, a été proposé pour une meilleure corrélation du comportement rhéologique des différents mélanges étudiés
